+Change logs are at :
 
-	* [libmultipath] default_prio and prio_callout keyword can be
-	  explicitly set to "none". Suggested by Kiyoshi Ueda, NEC
-	* [path_prio] don't exit pp_balance_units with error when
-	  find_controler() is not successful. It just means no other
-	  path is currently active on this controler.
-	* [path_prio] move balance_units in its own dir
-	* [multipathd] proactively fail_path upon checker up->down
-	  transitions. Suggested by Edward Goggin, EMC
-	* [libmultipath] .priority is clearly an int, not an unsigned
-	  int. /bin/false is now personna non grata as a prio callout.
-	  Kiyoshi Ueda, NEC
-	* [libmultipath] callout.c argv parsing fix. Kiyoshi Ueda,
-	  NEC
-	* [multipathd] check return codes in init_paths(), split out
-	  init_event().
-	* [libmultipath] add find_slot(vec, addr) to vector lib.
-	* [multipath] remove signal sending
-	* [multipathd] use uevent to do paths list housekeeping for
-	  checkers. Remove signal handling.
-	* [libmultipath] add uevent.[ch]
-
-2005-04-23 multipath-tools-0.4.4
-
-	* [path_prio] clarify pp_alua licensing. Stefan Bader, IBM.
-	* [devmap_name] add a target_type filter (suggested by Hannes)
-	  and set DM task device by major:minor rather than parsing
-	  the full map list.
-	* [libmultipath] propagate an error on getprio callout
-	  failures, so that multipath can mark the map as immutable.
-	  Reported by Lars Marowsky-Brée, Suse.
-	* [libmultipath] move push_callout() from dict.c to config.c
-	  Use it in store_hwe() to get in multipathd's ramfs the
-	  callout defined in hwtable.c when no config file is used.
-	  Reported by Lars Marowsky-Brée, Suse.
-	* [checkers] zero sense buffers before use in EMC checker.
-	  Lars Marowsky-Brée, Suse.
-	* [all] pre-release bugfixing effort from Alasdair, Hannes, 
-	  Lars, Benjamin Marzinski
-	* [multipathd] set oom_adj to -17 when kernel permits.
-	  Immune to OOM killer ? agk says : watch out for mem
-	  leaks :/
-	* [multipathd] safety nets from udevd : exit early if
-	  not root, chdir to / to avoid pining a mount.
-	* [multipathd] multipathd could loose events coming from
-	  sighup or DM waitev. Add a pending_event counter to
-	  track that.
-	* [path_prio] add pp_emc from Lars M Bree, Suse.
-	* [path_prio] add pp_alua from Stefan Bader, IBM.
-	* [libmultipath] add config.c:load_config(), which sucks
-	  a big chunk of code out of multipath/main.c.
-	* [libmultipath] don't allocate memory in :
-		* devmapper.c:dm_get_map()
-		* devmapper.c:dm_get_status()
-	* [libmultipath] devinfo() a la carte fetching
-	* [libmultipath] merge keepalived memory audit framework
-	  (Thanks again, M. Cassen). Already found and fixed a
-	  couple of leaks.
-	* [libmultipath] flatten/optimize dm_map_present() and
-	  dm_mapname(). Inspired by Alasdair Kergon, RedHat.
-	* [kpartx] dm_map_name() free before use bugfix. Kiyoshi
-	  Ueda, NEC
-	* [kpartx] add hotplug mode. To enable name the binary
-	  "kpartx.dev". Kiyoshi Ueda, NEC
-	* [multipathd] don't loose events in event waiter thread.
-	  Suggested and prototyped by Edward Goggin, EMC
-	* [libmultipath] add return values to vector manipulation
-	  fonctions. Mem alloc return code audit.
-	* [libmultipath] Use "config->udev_dir + path->dev" as
-	  a path devnode to open instead of mknod'ing for each
-	  one. Fix some DoS issues regarding usage of /tmp in
-	  libmultipath/discovery.c:opennode(). Kill unlinknode()
-	* [multipathd] merged the redhat init script and stop
-	  installing one on "make install"
-	* [libmultipath] fold safe_sprintf.h into util.h
-	* [libmultipath] move blacklist to a real regex matcher
-	  Example config files updated : check yours !!
-	* [multipath] fix path group compare logic to not stop
-	  comparing at first path in each PG.
-	* [multipathd] check if pidfile is a dead remnent of a
-	  crashed daemon. If so, overwrite it. Suggested by
-	  Alasdair Kergon, RedHat. Code heavily based on work
-	  by Andrew Tridgell, Samba Fame.
-	* [build] dropped libdevmapper/ and libsysfs/ from the
-	  package. klibc build is now broken until distributors
-	  provide klibc compiled static libraries in their
-	  respective packages.
-	* [libmultipath] dm_task_no_open_count() before each DM
-	  ioctl. Not doing that is reported to cause deadlocks
-	  in kernel-space. Reported by Edward Goggin, EMC, fix
-	  suggested by Alasdair Kergon, RedHat
-	  Note minimal libdevmapper version bumped up to 1.01.
-	* [multipath] switched to condlog(). "make DEBUG=N" is
-	  deprecated. Debug is spat with "-v3" or more.
-	* [multipathd] "multipathd -vN" cmdline arg to control
-	  daemon verbosity. 0 < N < 4. "make LOGLEVEL=N" is
-	  deprecated.
-	* [libmultipath] provide a common condlog() primitive to
-	  switch lib messages to syslog or stdout depending on
-	  who uses the lib (daemon or tool).
-	* [kpartx] give kpartx a private, slim copy of devmap.[ch]
-	* [multipath] allow wwid in blacklist{} config section.
-	  Kiyoshi Ueda, NEC.
-	* [multipathd] set mode value before use (S_IRWXU). Fixes
-	  RedHat Bugzilla Bug 150665.
-	* [all] add ->fd to "struct path *". remove fd from all
-	  checker context declaration. remove lots of duplicate
-	  logic. Now a fd is opened only once for path. It should
-	  also bring a bit safety in contended memory scenarii
-	* [libcheckers] remove redundant sg_include.h
-	* [libmultipath] merge multipath:dict.[ch] with
-	  multipathd:dict.[ch] into libmultipath/. move config.h
-	  there too, add some helper functions to alloc/free
-	  "struct config *" in a new config.c. Start using a
-	  config in the daemon.
-	* [libmultipath] move dm_geteventnr(), dm_get_maps() and
-	  dm_switchgroup() in devmapper.[ch]
-	* [libmultipath] move path discovery logic in
-	  libmultipath. merge devinfo.[ch] and sysfs_devinfo.[ch]
-	  into discovery.[ch]
-	* [libmultipath] move config.h in libmultipath. Move
-	  find_[mp|hw]e in a new config.c. Move "struct hwtable"
-	  declaration in config.h. Move propsel.[ch] in the
-	  lib too.
-	* [multipathd] use libmultipath:dm_type() instead of
-	  duplacate and bogus devmap discovery code.
-	* [multipathd] asynchronous & non-blocking logger
-	  thread. Implementation split into a generic log
-	  lib and a pthread wrapper for locking and events.
-	  An ipc wrapper could be easily created by
-	  interested parties.
-	* [multipath] add "multipath -l -v2 [devname|devt]"
-	  support in complement to [mapname|wwid]
-	* [kpartx] suppress loop.h private copy. Should fix
-	  the reported build problems
-	* [multipath] do sysfs_get_mnt_path() only one time
-	  and store in a global var.
-	* [multipath] further path discovery optimzation
-	* [multipath] purge superfluous includes in main.c
-	* [libmultipath] introduce a cache file. expiry set
-	  to 5 secondes to covert the hotplug event storms.
-	* [multipath] split get_pathvec_sysfs(). Introduce
-	  get_refwwid() and filter_pathvec()
-
-2005-03-19 multipath-tools-0.4.3
-
-	* [libmultipath] rename find_[mp|hw] to find_[mp|hw]e and
-	  introduce a real find_mp().
-	* [priority] provison for recursive compilation of prio
-	  subdirs, in preparation of merging more signicant
-	  prioritizers. Stephan Bader, IBM
-	* [libmultipath] add a netapp controler to the hwtable
-	* [libmultipath] blacklist() not to discard sda[0-9]*
-	  when sda is blacklisted
-	* [multipath] add a rr_min_io keyword in config file.
-	  Suggested by Igor Feoktistov, NetApp
-	* [multipath] stop trying to avoid running in parallel
-	* [multipath] bump up params size to 1024
-	* [multipathd] put prio callouts in to ramfs. Stephan
-	  Bader, IBM
-	* [multipath] simplify multibus pgpolicy : no need to
-	  copy mp->paths into mp->pg->paths then free source :
-	  just copy the ptr and set source to NULL.
-	* [multipath] sort PG by descending prio value in
-	  group_by_prio. Stephan Bader, IBM
-	* [multipath] fix a bug in group_by_prio that lead to
-	  creation of multiple PG for a single prio value
-	* [multipath] don't store multipaths in a vector anymore :
-	  free the "struct multipath" after usage.
-	* [multipath] multiple optimizations in the exec plan
-	* [multipath] allow "multipath -l -v2 [mapname|wwid]"
-	* [build] rip off klibc and move to klcc, at last.
-	  Good job hpa. multipath-tools now depend on klibc
-	  > 1.0 to build with BUILD=klibc flag.
-	* [multipath] never reload a map if no path is up in the
-	  computed new map
-	* [multipath] don't flush maps with open count != 0
-	* [libmultipath] add "int *dm_get_opencount(char *map)"
-	  to devmapper.c
-	* [multipath] plug leaks and optimize devinfo.c. From
-	  Edward Goggin, EMC
-	* [multipath] fix the multipath.dev hotplug script to not
-	  do kpartx stuff in the same run as multipath stuff.
-	  Igor Feoktistov, NetApp, noted the devmap symlink was
-	  not yet present for kpartx to use.
-	* [devmap_name] accept major:minor synthax
-	* [libmultipath] add "char *dm_mapname(int maj, int min)",
-	  needed to fail paths from checker thread
-	* [libmultipath] move dm_reinstate() in the lib, and add
-	  dm_fail_path()
-	* [multipathd] mark failed path as failed upon DM
-	  event. This should fix the design bug noticed by
-	  Ramesh Caushik, Intel, where the daemon didn't run
-	  multipath when a path went down and up in between 2
-	  checks.
-	* [libmultipath] allow NULL as a pathvec in disassemble_map
-	  as is passed only for memory optimization
-	* [libmultipath] add structs.c to store alloc_*() and
-	  free_*()
-	* [libmultipath] move dmparser.[ch] to the lib.
-	  remove devinfo.[ch] dependency.
-	* [build] fix compilation glitch with BUILD=klibc,
-	  flags to force use of local libs, remove the link
-	  dependency in klibc, try to guess kernel sources
-	  and build dirs. Stefan Bader, IBM
-	* [libmultipath] find_hw matching logic to take str
-	  lengths in account. Noticed by Ramesh Caushik, Intel
-	* [multipath] select_action matching logic to take str 
-	  length in account.
-	* [multipath] lookup mp alias name earlier (in coalesce)
-	  Edward Goggin, EMC, noticed we tried to use it before
-	  it was set up.
-
-2005-01-23 multipath-tools-0.4.2
-
-	* [libmultipath] add symmetrix controler family to the
-	  hwtable. Edward Goggin, EMC
-	* [libmultipath] factorize core structs (path, ...)
-	  and defaults (pidfile, configfile, ...). Convert
-	  callers.
-	* [multipath] fix dmparser to properly fetch non-default
-	  hwhandler. Edward Goggin, EMC
-	* [multipath] fix devt2devname matching 8:1 with 8:10
-	  for example. Edward Goggin, EMC
-	* [multipath] switch_pg upon devmap create or reload
-	  Noticed by Ake.
-	* [libmultipath] move find_hw() the library. Convert
-	  users. Now multipathd understand '*' as a product
-	  string
-	* [multipath] dissaemble_map() fix to avoid to
-	  interpret 'D' as a disable PG (not 'F'). Edward
-	  Goggin, EMC
-	* [multipath] find_path() fix to avoid matching 8:1
-	  with 8:10 for example. Edward Goggin, EMC
-	* [libmultipath] move some sysfs fetching routines
-	  to library, under sysfs_devinfo.[ch]. Convert
-	  callers.
-	* [multipath] fix -v0 : avoids the daemon waiting
-	  for the initial multipath run to complete, which
-	  will never happen because of a flooded pipe
-	* [multipathd] add scsi_id to default binvec
-	* [libmultipath] move hwtable related logic to the
-	  library. Convert multipath and multipathd
-	* [multipath] move first blacklist call down after
-	  setup_default_blist()
-	* [libmultipath] move basename() to the lib. Convert
-	  multipath and multipathd.
-	* [libmultipath] move blacklist related logic to the
-	  library. Convert multipath and multipathd
-	* [multipath] fix bug in the default hardware table
-	  matching logic (Lars M-B, Suse)
-	* [multipath] allow "*" as scsi model string wildcard
-	  (Lars M-B, Suse)
-	* [multipath] provide a macro to fill all hwe fields,
-	  use it to declare Clariion models (Lars M-B, Suse)
-	* [multipath] use DEFAULT_GETUID instead of hardcoded
-	  *and* incorrect "/bin/scsi_id -g -s" (Lars M-B, Suse)
-	* [multipath] kill superfluous suspend before table
-	  reload. The code was unsafe, as spotted by Edward
-	  Goggin (EMC)
-	* [multipath] exit early if device parameter is
-	  blacklisted
-	* [multipath] don't check for prefix in initrd's
-	  multipath.dev : this is the tool responsability to
-	  exit early based on its blacklist.
-	* [multipath] don't signal the daemon in initrd
-	  (Guido Guenther, Debian tracker)
-	* [multipath] better fail to run kpartx in initrd
-	  than crashing the whole system. So don't sleep
-	  waiting for udev to create the DM node. Maybe udev
-	  has made progress I this regard ... (noticed by
-	  Paul Wagland, Debian tracker)
-	* [multipath] don't reinstate when listing, ie list
-	  implies dry_run
-	* [checkers] fix the emc checker (Hergen Lange)
-	* [multipath] node_name fetching shouldn't exit on
-	  error. FC SAN are not the only multipathed context
-	  (noticed by Ramesh Caushik)
-
-2004-12-20 multipath-tools-0.4.1
-

-	  (Hergen Lange)
-	* [checkers] treat the emc checker in the name to 
-	  index translator function (Hergen Lange)
-	* [multipath] print to stderr DM unmet requirement
-	  (Guido Guenther)
-	* [multipath] fix realloc return value store not
-	  propagated to caller by merge_word() (Nicola Ranaldo)
-
-2004-12-10 multipath-tools-0.4.0
-
-	* [checkers] forgot to return back to caller the newly
-	  allocated context. Lead to fd leak notably.
-	* [checkers] heavy check logic fix
-	* [checkers] really malloc the checker context size,
-	  not the pointer size (stupidy may kill)
-	* [multipathd] check more sysfs calls return values
-	* [multipathd] search for sysfs mount point only once,
-	  not on each updatepaths() iteration
-	* [multipathd] plug (char *) leak in the daemon
-	* [multipath] change pgcmp logic : we want to reload a
-	  map only if a path is in computed map but not in cur
-	  map (ie accept to load a map if it brings more paths)
-	* [multipath] undust coalesce_paths()
-	* [multipath] don't print unchanged multipath
-	* [multipath] store the action to take in the multipath
-	  struct
-	* [multipath] print mp size with kB, MB, GB or TB units
-	* [multipath] compilation fix for merge_words() (Andy)
-	* [multipath] don't feed the kernel DM maps with paths of
-	  different sizes : DM fails and we end up with an empty
-	  map ... not fun
-	* [multipath] cover a new corner case : path listed in
-	  status string but disappeared from sysfs
-	* [multipath] remove the "-D" command line flag : now
-	  we can pass major:minor directly as last argument, like
-	  device names or device map names. Update multipathd
-	  accordingly.
-	* [multipath] try reinstate again paths after a switchpg
-	* [multipath] reinstate condition change : 
-
-2004-12-05 multipath-tools-0.3.9
-
-	* [multipath] add a "-l" flag to list the current
-	  multipath maps and their status info
-	* [priority] zalloc controler to avoid random path_count
-	  at allocation time
-	* [multipath] add configlet pointers in struct multipath
-	  to avoid searching for an entry over and over again
-	* [multipath] new reinstate policy : on multipath exec,
-	  reinstate all failed paths the checkers report as ready
-	  if they belong to enabled path groups (not disabled, not
-	  active path group)
-	* [multipath] fork a print_mp() out of print_all_mp()
-	* [multipath] introduce PG priority, which is the sum of
-	  its path priorities. Set first_pg in the map string to
-	  the highest prio PG index.
-	* [multipath] assemble maps scaning PG top down now that
-	  PG vector is unsorted
-	* [multipath] move select_*() to propsel.c
-	* [multipath] move devinfo() to devinfo.c
-	* [multipath] move h/b/t/l fetching to sysfs_devinfo()
-	* [multipath] move devt2devname() to devinfo.c so we can
-	  use it from dmparser.c too
-	* [multipath] introduce select_alias() and clarify a bit
-	  of code
-	* [multipath] don't sort PG anymore. We want the map as
-	  static as possible.
-	* [multipath] fix a segfault in apply_format() triggered
-	  when no config file found.
-	* [multipath] kill unused vars all over the place
-	* [multipath] add a struct pathgroup in struct multipath
-	  Store the pathvec in it. We now have a place to store
-	  PG status, etc ...
-	* [multipath] new dmparser.c, with disassemble_map(),
-	  disassemble_status()
-	* [multipath] suppress *selector_args keywords. Merge
-	  in the selector string. Update config file templates.
-
-2004-11-26 multipath-tools-0.3.8
-
-	* [priority] teach multipath to read callout keywords
-	  formatted as /sbin/scsi_id -g -u -s /block/%n
-	  Apply one substitutions out of :
-		* %n : blockdev basename (ie sdb)
-		* %d : blockdev major:minor string (ie 8:16)
-	  update sample config files
-	* [priority] fix find_controler(). Now works, verified
-	  on IBM T200 at OSDL (thanks again, Dave). Add to the
-	  main build process
-	* [multipath] add a controler specific "prio_callout"
-	  keyword. Noticed by Ake
-	* [multipath] normalize the debug ouput
-	* [multipath] add select_getuid(). De-spaghetti
-	  devinfo() thanks to that helper.
-	* [libmultipath] add VECTOR_LAST_SLOT macro.
-	  multipath/dict.h now use it heavily.
-	* [multipath] policies selectors speedup and cleanup
-	  (pgpolicy, features, hwhandler, selector)
-	* [multipath] new "flush" command flag
-	* [libmultipath] add dm_type() and dm_flush_maps()
-	* [multipath] move dm_get_map() to libmultipath
-	* [multipath] rename iopolicy to pgpolicy everywhere.
-	  Dual terminology was getting confusing.
-	* [multipath] assemble_map() to always set next_pg to 1
-	  for now.
-	* [multipath] update config file to show new keywords.
-	  Add an IBM array tested at OSDL.
-	* [multipath] fork select_iopolicy() from setup_map()
-	* [multipath] introduce select_features() and 
-	  select_hwhandler(). Should merge select_* one day ...
-	* [multipath] add features and hardware_handler keywords
-	  and use them in the map setup
-	* [build] make clean really clean. Noticed by Dave Olien,
-	  OSDL
-	* [multipath] group_by_serial bugfix
-	* [multipath] dm_addmap() return value fix. Now multipath
-	  really creates the maps
-	* [multipath] try dm_log_init_verbose() instead of dup()
-	  + close() to silence libdevmapper (Ake at umu)
-	* [libcheckers] remove checkpath() wrapper, obsoleted by
-	  the "fd in context" changes
-	* [multipathd] let pathcheckers allocate their context.
-	  No more over or unneeded allocation.  Suggested by Lars,
-	  Suse
-	* [multipathd] store the pathcheckers fd in their context.
-	  No more open / close on each check. Suggested by Lars,
-	  Suse
-
-2004-11-05 multipath-tools-0.3.7
-
-	* [multipathd] fix off by one memory allocation (Hannes,
-	  Suse)
-	* [multipathd] introduce a default callout handler that
-	  just remembers to put the callout in ramfs, even if the
-	  daemon has no direct use of them. multipath need some
-	  that where forgotten, so parse them and use that default
-	  handler.
-	* [libcheckers] emc_clariion checker update (Lars, Suse)
-	* [build] exit build process on failure (Lars, Suse)
-	* [kpartx] exit early if DM prereq not met
-	* [multipath] exit early if DM prereq not met
-	* [libmultipath] new dm_prereq() fn to check out if all DM
-	  prerequisites are met
-	* [libmultipath] move callout.[ch] function in there.
-	  multipath and multipathd impacted
-	* [libmultipath] move dm_* function in there. kpartx,
-	  multipath are impacted
-	* [priority] pp_balance_lun should use DM_DEVICE_TABLE ioctl
-	  instead of DM_DEVICE_STATUS to find out paths from the
-	  primary path groups.
-	* [klibc] drop in "Stable" version 0.190
-	* [build] add manpages for kpartx and multipathd (Patrick
-	  Caulfield)
-	* [build] use system's sysfs for multipathd linking
-	* [build] make glibc the default build
-	* [build] "make BUILD=klibc" is enough, deprecate the 
-	  "make BUILD=klibc klibc" synthax
-
-2004-10-30 multipath-tools-0.3.6
-
-	* Patrick Caulfield took over debian packaging. Showing
-	  evident expertise, his first wish is to see debian/
-	  disappear. :) So be it.
-	* [libmultipath] add a vector_foreach_slot macro. Still
-	  needs an iterator but saves 1 line per loop occurence and
-	  tame this UPPERCASE MACROS bad taste.
-	* [multipathd] don't load sg anymore on multipathd startup
-	* [multipathd] change killall for kill `cat $PIDFILE` in
-	  init script (Jaime Peñalba & Cesar Solera)
-	* [multipathd] the fork fallback was borked (just exiting)
-	  noticed by Jaime Peñalba & Cesar Solera
-	* [multipathd] try without the FLOATING_STACKS flag. Does
-	  it matter anyway ?
-	* [multipathd] merge clone_platform.h from LTP and cover
-	  the hppa special case.
-	* [multipath] since we will be able to create a devmap with
-	  paths too small, don't rely anymore on the first path's
-	  size blindly : verify the path is up, before assigning its
-	  size to the multipath
-	* [priority] add a path priority fetcher to balance LU accross
-	  controlers based on the controler serial detection. Untested
-	  but provides a good example of what can be done with the
-	  priority framework.
-	* [priority] create subdir and drop a test pp_random
-	* [multipath] add dev_t reporting to print_path() to ease
-	  devmap decoding by humans
-	* [multipath] change default path priority to 1
-	* [multipath] add wits to the sort_by_prio policy, so that
-	  sort_pathvec_by_prio() is now useless. Remove it.
-	* [multipath] invert sort_pg_by_summed_prio sort order :
-	  highest prio leftmost
-	* [libmultipath] add vector_del_slot
-	* revert multipath.rules change : devmap_name still takes
-	  "major minor" and not "major:minor" as argument
-	* Makefile refinement : you can now enter any tool directory
-	  and build from here, deps are solved
-
-2004-10-26 multipath-tools-0.3.5
-
-	* [multipathd] fix broken test for path going up or shaky
-	  that kept executing multipath when it shouldn't
-	* change multipath.dev to exit early when udev' DEVNAME is
-	  a devmap (/dev/dm-*). This avoids a recursion case when
-	  the kernel devmapper keeps removing a map after multipath
-	  configures it.
-	* change multipath.rules to follow the new -D synthax
-	* [multipath] "-D major minor" synthax changed to 
-	  "-D major:minor" to match the sysfs attribute value.
-	  This change removes a few translations in multipath and
-	  multipathd.
-	* [multipath] fix segfault in test if conf->dev is a devmap
-	  (the one forwarded by MikeAnd)

-	  failed path priority
-
-2004-10-26 multipath-tools-0.3.4
-
-	* [multipathd] exec multipath precisely : pass in the path
-	  or the devmap to update. No more full reconfiguration, and
-	  really use the reinstate feature of multipath.
-	* [multipathd] check all paths, not only failed ones. Path
-	  checker now trigger on state change (formerly triggred on
-	  state == UP condition)
-	* [multipathd] incremental updatepaths() instead of scrap /
-	  refresh all logic.
-	* [multipathd] path checkers now take *msg and *context
-	  params. consensus w/ lmb at suse. tur.c modified as example
-	* [multipath] assemble maps in PG vector descending order to
-	  fit the layered policies design
-	* [multipath] stop playing with strings in pgpolicies, as it
-	  uses more memory and looses info for no gain
-	* [multipath] remove lk2.4 scsi ioctl scsi_type remnant
-	* [multipath] layered pgpolicies : (see pgpolicies.c)
-		* group_by_status
-		* group_by_serial | multibus | failover | group_by_prio
-		* sort_pg_by_summed_prio
-	  thus remove duplicated failedpath logic in pgpolicies
-	* [libmultipath] add vector_insert_slot
-	* [checkers] framework for arbitrate checkers return values
-	* [multipathd] scrap yet another reinvented wheel in the 
-	  name of the LOG macro :  learn the existance of setloglevel
-	  and LOG_UPTO macro
-	* glibc make with "make BUILD=glibc", asked by lmb at suse
-
-2004-10-20 multipath-tools-0.3.3
-
-	* [checkers] add the emc_clariion path checker (lmb at Suse)
-	* [multipath] introduce safe_snprintf macro to complement the
-	  safe_sprintf. Needed to cover the sizeof(pointer) cases
-	  pointed by Dave Olien at OSDL
-	* [multipath] move to the common libchecker framework and
-	  activate the selector
-	* [multipath] fix an iopolicy selector bug (initialized lun
-	  iopolicy overrode controler-wide iopolicy)
-	* [multipathd] cleanly separate out the checker selector, as
-	  done with iopolicy selector
-	* [multipathd] move out the checkers into a common libcheckers
-	* [multipath] fix the anti-parallel-exec logic : use a write 
-	  lease for the task. From Dave Olien at osdl.
-	* [multipath] fix reinstate : pass a devt, not a devname
-
-2004-10-16 multipath-tools-0.3.2
-
-	* [multipath] add path reinstate logic :
-		* if a path is given as multipath arg
-		* if the map containing that path already exists
-		* if this map is the same as the that would be
-		  created by this multipath run
-		* THEN reinstate the path
-	  multipathd is is thus unchanged, while now supporting
-	  reinstate
-	* audit and ensafe all sprintf usage
-	* [multipath] fix the annoying \n after each dev_t in
-	  params string reporting
-	* [multipath] print out devmaps in "-v2 -d" mode

-	* [kpartx] replace sprintf by snprintf (lmb at suse)
-	* [kpartx] initialize some more vars (lmb at suse)
-	* [multipath] mp->pg == NULL safety net before calling
-	  assemble_map() (for Andy who happen to hit the bug)
-	* [multipath] last rampant bug in map CREATE or UPDATE switch
-	  logic due to the device alias feature
-	* [kpartx] zeroe "struct slice all" (lmb at suse)
-
-2004-10-11 multipath-tools-0.3.1
-
-	* [kpartx] move back to getopt, originaly removed from the 
-	  original partx because of lack of implementation in klibc
-	* [kpartx] don't map extended partitions
-	* [kpartx] add a -p command flag to allow admin to force a
-	  delimiting string between disk name and part number. When
-	  specified always use it, when unspecified use 'p' as a delim
-	  when last char of disk name is a digit, NUL otherwise.
-	* [kpartx] clean up
-	* bump klibc to 0.182
-	* one step further : use klibc MCONFIG for all klibc specific
-	  FLAGS definitions, ie massive Makefile.inc cleanup
-	* follow the klibc compilation rules by appending its OPTFLAGS
-	  to multipath-tools' CFLAGS. This corrects the segfaults seen
-	  on i386 where klibc is built with regparm=3 and tools are not

-	  like in Debian Woody
-	* [kpartx] move .start and .size from uint to ulong (Ake)

-
-2004-10-06 multipath-tools-0.3.0
-
-	* first cut at making scripts to create multipath-aware initrds
-	  those scripts are tested on Debian SID, and must be copied into
-	  /etc/mkinitrd/scripts. it works here.
-	* [multipath] verify presence of the /sys/block/... node before
-	  reading sysfs attributes. Avoids libsysfs and scsi_id stderr
-	  garbage
-	* [multipath] move down the stderr close (Ake Sandgren at umu.se)
-	* [multipath] don't care about 0-sized mp (Ake Sandgren at umu.se)
-	* [multipath] bump mp size field to ulong (Ake Sandgren at umu.se)
-	* [multipath] replace quiet/verbose flags by a verbosity one.
-	  introduce a new verbosity level : 1 == print only devmap names
-	  thus we can feed kpartx with that output
-	* [multipath] update man page to reflect the hotplug.d -> dev.d
-	  transition and replace the obsolete group_by_tur policy by the
-	  forgotten group_by_prio
-	* [multipath] provide a /etc/udev/rules.d/multipath.rules for
-	  multipath devices naming. Cleaner than the previously suggested
-	  rule addition in the main udev.rules
-	* [multipath] move out of hotplug.d to dev.d : kill synchronisation
-	  problems between device node creation and multipath execution.
-	  Incidentally the unfriendly $DEVPATH param become a friendly
-	  $DEVNAME (simply /dev/sdb)

-		* endianness fixes
-		* push the partname string size to handle wwwids
-		* quieten implicit cast warnings
-	* [multipath] add an 'alias' multipath keyword for friendlier device
-	  names. This was "asked" by OSDL' CGL board of secret reviewers
-	* [multipath] last pass with JBOD and parallel SCSI support :
-	  hard-code scsi_id as a fallback when disk strings doesn't match
-	  any hwtable entry
-	* [multipath & multipathd] change the parser to not coalesce
-	  consecutive spaces (Patrick Mansfield)
-	* [multipath] remove the [UN]: output prefix, so that stdout can be
-	  easily fed to a tool like dmsetup
-	* [multipathd] DEBUG=3 logs more readable/usefull
-	* [multipathd] add a multipath_tool config keyword
-	* [multipathd] move to execute_program() like multipath already did
-	* [multipath] don't print the "no path" msg in quiet mode
-	* [multipathd] include linux/unistd.h for _syscall2
-	  definition on RedHat systems. Remove superfluous
-	  asm/unistd.h include
-	* [libsysfs] forked : last version uses mntent, which
-	  klibc doesn't provide. That, plus the fact we use
-	  only 1/3 of the lib, pushed me to freeze the version
-	  and strip all unused stuff.
-	* [multipathd] prepare_namespace() cleanup : no more "multipath"
-	  special casing since we push it to binvec vector, like the other
-	  callouts detected in the config file.
-
-2004-08-13 multipath-tools-0.2.8
-
-	* [multipathd] setsched prio to RT

-	  <genanr@emsphone.com>
-	* [multipath] clean up failed devmap creation attempt
-	* [libs] update to libdevmapper 1.00.19
-	* [multipath] framework for claimed device skipping
-	  still lacks a reliable way to know if the device is
-	  claimed and by who (fs, swap, md, dm, ...). If you
-	  think it is valid to let libdevmapper hit the wall,
-	  please speak up and tell so.
-	* [multipath] shut down stderr when calling into libdm
-	* [multipath] reformat the verbose output
-	* [multipath] framework for path priority handling (ALUA)
-	* [multipath] kill all reference to group_by_tur

-	* [multipath] fix segfault when pathvec is empty after
-	  get_pathvec()
-	* move to template based specfile to avoid regular version skew

-
-2004-06-14 multipath-tools-0.2.3
-
-	* [multipath] group_by_serial try to be smart with LUN
-	  balancing across controlers (for STK / LSI) :
-	  1st multipath : 1st pg made of path through 1st controler
-	  2nd multipath : 1st pg made of path through 2nd controler
-	  3rd multipath : 1st pg made of path through 1st controler
-	  ...
-	* [multipath] drop .pindex[] in struct multipath in favor

-	  on IA64. Remove the needless optimisation for now.
-
-2004-06-05 multipath-tools-0.2.1
-
-	* [multipath] add a flag to inihibit the final SIGHUP to

-	* remove useless "int with_sysfs" in env struct 
-
-2004-02-04 multipath-016
-
-	* add a GROUP_BY_SERIAL flag. This should be useful for
-	  controlers that activate they spare paths on simple IO
-	  submition with a penalty. The StorageWorks HW defaults to
-	  this mode, even if the MULTIBUS mode is OK.
-	* remove unused sg_err.c
-	* big restructuring : split devinfo.c from main.c. Export :
-		* void basename (char *, char *);
-		* int get_serial (int, char *);
-		* int get_lun_strings (char *, char *, char *, char *);
-		* int get_evpd_wwid(char *, char *);
-		* long get_disk_size (char *);

-
-2003-12-22 multipath-010
-
-	* tweak the install target in Makefile
-	* stop passing fds as argument : this change enable a strict
-	  segregation of ugly 2.4 code
-	* sysfs version of get_lun_strings()
-	* be careful about the return of get_unique_id() since errors 
-	  formerly caught up by if(open()) in the caller fn are now returned
-	  by get_unique_id()
-	* send get_serial() in unused.c
-	* introduce dm-simplecmd for RESUME & SUSPEND requests
-	* split add_map() in setup_map() & dm-addmap()
-	* setup_map() correctly submits "SUSPEND-RELOAD-RESUME or CREATE"
-	  sequences instead of the bogus "RELOAD or CREATE"
-	* don't print .sg_dev if equal to .dev (2.6) in print_path()
-	* since the kernel code handles defective paths, remove all
-	  code to cope with them :
-		* move do_tur() to unused.c
-		* remove .state from path struct
-		* remove .state settings & conditionals
-	* add a cmdline switch to force maps to failover mode,
-	  ie 1 path per priority group
-	* add default policies to the whitelist array (spread io ==
-	  MULTIBUS / io forced to 1 path == FAILOVER)
-	* move get_disk_size() call out of add_map() to coalesce()
-	* comment tricky coalesce() fn
-	* bogus unsused.c file renamed to unused.c
-
-2003-12-20 multipath-010
-
-	* big ChangeLog update
-	* start to give a little control over target params :
-	  introduce cmdline arg -i to control polling interval
-	* cope with hotplug-style calling convention :
-	  ie "multipath scsi $DEVPATH" ... to avoid messing with
-	  online maps not concerned by an event
-	* example hotplug agent to drop in /etc/hotplug.d/scsi
-	* revert the run & resched patch : unless someone proves me
-	  wrong, this was overdesigned
-	* move commented out functions in unused.c
-	* update multipath target params to "udm[23] style"
-	* mp target now supports nr_path == 1, so do we
-	* add gratuitous free()
-	* push version forward
-
-2003-12-15 multipath-009
-
-	* Make the HW-specific get_unique_id switch pretty
-	* Prepare to field-test by whitelisting all known fibre array,
-	  try to fetch WWID from the standard EVPD 0x83 off 8 for everyone
-	* configure the multipath target with round-robin path selector and
-	  conservative default for a start (udm1 style) :
-	  yes it makes this release the firstreally useful one.
-	* temporarily disable map creation for single path device
-	  due to current restrictive defaults in the kernel target.
-	  Sistina should work it out.
-	* correct the strncmp logic in blacklist function.
-	* update the Makefiles to autodetect libgcc.a & gcc includes
-	  "ulibc-style". Factorisation of udevdirs & others niceties
-	* drop a hint about absent /dev/sd? on failed open()
-	* implement a reschedule flag in /var/run.
-	  Last thing the prog do before exit is check if a call to multipath
-	  was done (but canceled by /var/run/multipath.run check) during its
-	  execution. If so restart themain loop.
-	* implement a blacklist of sysfs bdev to not bother with for now
-	  (hd,md, dm, sr, scd, ram, raw).
-	  This avoid sending SG_IO to unappropiate devices.
-	* Adds a /var/run/multipath.run handling to avoid simultaneous runs.
-	* Remove a commented-out "printf"
-	* drop a libdevmapper copy in extras/multipath;
-	  maybe discussions w/Sistina folks will bring a better solution
-	  in the future.
-	* drop a putchar usage in libdevmapper to compile cleanly with klibc
-	* drop another such usage of my own in main.c
-	* massage the Makefile to compile libdevmapper against klibc
-	* use "ld" to produce the binary rather than "gcc -static"
-	* stop being stupid w/ uneeded major, minor & dev in main.c:dm_mk_node()
-	* reverse to creating striped target for now because the multipath
-	  target is more hairy than expected initialy
-	* push the version code to 009 to be in synch w/ udev
-
-2003-11-27 multipath-007
-
-	* removes sg_err.[ch] deps
-	* makes sure the core code play nice with klibc
-	* port the sysfs calls to dlist helpers
-	* links against udev's sysfs (need libsysfs.a & dlist.a)
-	* finally define DM_TARGET as "multipath" as Joe posted the code today
-	  (not tested yet)
-	* push version forward (do you want it in sync with udev version?)
-
-2003-11-19 multipath-006
-
-	* merged in udev-006 tree
