2005-11-07[PATCH] kfree cleanup: fsJesper Juhl5-92/+45

2005-10-27[CIFS] Change pragma pack(1) to attribute(packed) to allow cifs on arm to accessSteve French3-186/+182
unaligned structures coming in off the wire gcc on arm processors generates very odd code with pragma pack specified - although it does pack the structures in some sense - it does not allow you to access unaligned elements in nested structures at the right offset as other architectures do. Oddly enough though, specifying the structures as packed the long way - one by one with the packed attribute does work. Rather than fighting over whether this is a gcc bug or some obscure side effect of pragma pack, it is easier to do what most (all but 96 other places in the kernel) do - and replace pragma pack with dozens of attribute(packed) structure qualifiers. Much more verbose ... but at least it works.

2005-08-26[PATCH] Fix oops in fs/locks.c on close of file with pending locksSteve French1-1/+1
The recent change to locks_remove_flock code in fs/locks.c changes how byte range locks are removed from closing files, which shows up a bug in cifs. The assumption in the cifs code was that the close call sent to the server would remove any pending locks on the server on this file, but that is no longer safe as the fs/locks.c code on the client wants unlock of 0 to PATH_MAX to remove all locks (at least from this client, it is not possible AFAIK to remove all locks from other clients made to the server copy of the file). Note that cifs locks are different from posix locks - and it is not possible to map posix locks perfectly on the wire yet, due to restrictions of the cifs network protocol, even to Samba without adding a new request type to the network protocol (which we plan to do for Samba 3.0.21 within a few months), but the local client will have the correct, posix view, of the lock in most cases. The correct fix for cifs for this would involve a bigger change than I would like to do this late in the 2.6.13-rc cycle - and would involve cifs keeping track of all unmerged (uncoalesced) byte range locks for each remote inode and scanning that list to remove locks that intersect or fall wholly within the range - locks that intersect may have to be reaquired with the smaller, remaining range.
