* [PATCH] aio: kiocb locking to serialise retry and cancelBenjamin LaHaise2005-09-091-4/+25
| | | | | | | | | | | | Implement a per-kiocb lock to serialise retry operations and cancel. This is done using wait_on_bit_lock() on the KIF_LOCKED bit of kiocb->ki_flags. Also, make the cancellation path lock the kiocb and subsequently release all references to it if the cancel was successful. This version includes a fix for the deadlock with __aio_run_iocbs.

* [PATCH] change io_cancel return code for no cancel caseWendy Cheng2005-09-091-1/+1
| | | | | | | | | | | | | | | | Note that other than few exceptions, most of the current filesystem and/or drivers do not have aio cancel specifically defined (kiob->ki_cancel field is mostly NULL). However, sys_io_cancel system call universally sets return code to -EAGAIN. This gives applications a wrong impression that this call is implemented but just never works. We have customer inquires about this issue. Changed by Benjamin LaHaise to EINVAL instead of ENOSYS Signed-off-by: S.

| | | | | | | | | | | | | | This patch removes the inode_post_create/mkdir/mknod/symlink LSM hooks as they are obsoleted by the new inode_init_security hook that enables atomic inode security labeling. If anyone sees any reason to retain these hooks, please speak now. Also, is anyone using the post_rename/link hooks; if not, those could also be removed.

* [PATCH] update filesystems for new delete_inode behaviorMark Fasheh2005-09-0919-0/+29
| | | | | | | | | | | | | | Update the file systems in fs/ implementing a delete_inode() callback to call truncate_inode_pages(). One implementation note: In developing this patch I put the calls to truncate_inode_pages() at the very top of those filesystems delete_inode() callbacks in order to retain the previous behavior. I'm guessing that some of those could probably be optimized.

* [PATCH] move truncate_inode_pages() into ->delete_inode()Mark Fasheh2005-09-091-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow file systems supporting ->delete_inode() to call truncate_inode_pages() on their own. OCFS2 wants this so it can query the cluster before making a final decision on whether to wipe an inode from disk or not. In some corner cases an inode marked on the local node via voting may not actually get orphaned. A good example is node death before the transaction moving the inode to the orphan dir commits to the journal. Without this patch, the truncate_inode_pages() call in generic_delete_inode() would discard valid data for such inodes. During earlier discussion in the 2.6.13 merge plan thread, Christoph Hellwig indicated that other file systems might also find this useful. IMHO, the best solution would be to just allow ->drop_inode() to do the cluster query but it seems that would require a substantial reworking of that section of the code. Assuming it is safe to call write_inode_now() in ocfs2_delete_inode() for those inodes which won't actually get wiped, this solution should get us by for now. Trivial testing of this patch (and a related OCFS2 update) has shown this to avoid the corruption I'm seeing.
