2005-06-25[PATCH] Cleanup patch for process freezingChristoph Lameter2-6/+6
1. Establish a simple API for process freezing defined in linux/include/sched.h: frozen(process) Check for frozen process freezing(process) Check if a process is being frozen freeze(process) Tell a process to freeze (go to refrigerator) thaw_process(process) Restart process frozen_process(process) Process is frozen now 2. Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE. This is not clean in an SMP environment. freeze(process) is therefore not SMP safe! Signed-off-by: Christoph Lameter <christoph@lameter.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-03JFS: Fix compiler warning in jfs_logmgr.cDave Kleikamp1-2/+3
fs/jfs/jfs_logmgr.c: In function `jfs_flush_journal': fs/jfs/jfs_logmgr.c:1632: warning: unused variable `mp' Some debug code in jfs_flush_journal does nothing when CONFIG_JFS_DEBUG is not defined. Place the whole code segment within an ifdef to avoid unnecessary code to be compiled and the warning to be issued. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

2005-05-02[PATCH] JFS: Don't allocate extents that overlap existing extentsDave Kleikamp3-25/+46
Modify xtSearch so that it returns the next allocated block when the requested block is unmapped. This can be used to make sure we don't create a new extent that overlaps the next one. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-02[PATCH] JFS: Write journal sync points more oftenDave Kleikamp4-9/+27
This patch adds jfs_syncpt, which calls lmLogSync to write sync points to the journal both in jfs_sync_fs and when sync barrier processing completes. lmLogSync accomplishes two things: 1) it pushes logged-but-dirty metadata pages to disk, and 2) it writes a sync record to the journal so that jfs_fsck doesn't need to replay more transactions than is necessary.

2005-05-02[PATCH] JFS: Changes for larger page sizeDave Kleikamp3-28/+39
JFS code has always assumed a page size of 4K. This patch fixes the non-pagecache uses of pages to deal with larger pages. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-02[PATCH] JFS: Simplify creation of new iagDave Kleikamp1-34/+36
JFS was creating a new IAG (inode aggregate group) in one address space, and afterwards, accessing it from another. This could lead to complications when cache pages contain more than one page of jfs metadata. This patch causes the IAG to be initialized in the same address space that it is subsequently accessed with. This also elimitates an I/O, but IAG's aren't created too often.

2005-05-02[PATCH] JFS: reduce number of synchronous transactionsDave Kleikamp1-23/+40
Use an inline pxd list rather than an xad list in the xadlock. When the number of extents being modified can fit with the xadlock, a transaction can be committed asynchronously. Using a list of pxd's instead of xad's allows us to fit 4 extents, rather than 2. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds44-0/+33077
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
