* [XFS] optimize xfs_ichgtimeChristoph Hellwig2008-08-131-6/+13
| | | | | | | | | | | | | Port a little optmization from file_update_time to xfs_ichgtime, and only update the timestamp and mark the inode dirty if the timestamp actually changes in the timer tick resultion supported by the running kernel.

* [XFS] update timestamp in xfs_ialloc manuallyChristoph Hellwig2008-08-134-21/+9
| | | | | | | | | | | | | | | | | In xfs_ialloc we just want to set all timestamps to the current time. We don't need to mark the inode dirty like xfs_ichgtime does, and we don't need nor want the opimizations in xfs_ichgtime that I will introduce in the next patch. So just opencode the timestamp update in xfs_ialloc, and remove the new unused XFS_ICHGTIME_ACC case in xfs_ichgtime.

* [XFS] extend completions to provide XFS object flush requirementsDavid Chinner2008-08-131-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XFS object flushing doesn't quite match existing completion semantics. It mixed exclusive access with completion. That is, we need to mark an object as being flushed before flushing it to disk, and then block any other attempt to flush it until the completion occurs. We do this but adding an extra count to the completion before we start using them. However, we still need to determine if there is a completion in progress, and allow no-blocking attempts fo completions to decrement the count. To do this we introduce: int try_wait_for_completion(struct completion *x) returns a failure status if done == 0, otherwise decrements done to zero and returns a "started" status. This is provided to allow counted completions to begin safely while holding object locks in inverted order. int completion_done(struct completion *x) returns 1 if there is no waiter, 0 if there is a waiter (i.e. a completion in progress). This replaces the use of semaphores for providing this exclusion and completion mechanism.

* [XFS] sanitize xfs_initialize_vnodeChristoph Hellwig2008-08-136-126/+111
| | | | | | | | | | | | | | | | | | | | | Sanitize setting up the Linux indode. Setting up the xfs_inode <-> inode link is opencoded in xfs_iget_core now because that's the only place it needs to be done, xfs_initialize_vnode is renamed to xfs_setup_inode and loses all superflous paramaters. The check for I_NEW is removed because it always is true and the di_mode check moves into xfs_iget_core because it's only needed there. xfs_set_inodeops and xfs_revalidate_inode are merged into xfs_setup_inode and the whole things is moved into xfs_iops.c where it belongs.

* [XFS] kill xfs_lock_dir_and_entryChristoph Hellwig2008-08-133-133/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | When multiple inodes are locked in XFS it happens in order of the inode number, with the everything but the first inode trylocked if any of the previous inodes is in the AIL. Except for the sorting of the inodes this logic is implemented in xfs_lock_inodes, but also partially duplicated in xfs_lock_dir_and_entry in a particularly stupid way adds a lock roundtrip if the inode ordering is not optimal. This patch adds a new helper xfs_lock_two_inodes that takes two inodes and locks them in the most optimal way according to the above locking protocol and uses it for all places that want to lock two inodes. The only caller of xfs_lock_inodes is xfs_rename which might lock up to four inodes.

* [XFS] Use KM_NOFS for incore inode extent tree allocation V2David Chinner2008-08-131-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we allow incore extent tree allocations to recurse into the filesystem under memory pressure, new delayed allocations through xfs_iomap_write_delay() can deadlock on themselves if memory reclaim tries to write back dirty pages from that inode. It will deadlock in xfs_iomap_write_allocate() trying to take the ilock we already hold. This can also show up as complex ABBA deadlocks when multiple threads are triggering memory reclaim when trying to allocate extents. The main cause of this is the fact that delayed allocation is not done in a transaction, so KM_NOFS is not automatically added to the allocations to prevent this recursion. Mark all allocations done for the incore inode extent tree as KM_NOFS to ensure they never recurse back into the filesystem.
