* xfs: fix ->write_inode return valuesChristoph Hellwig2011-09-01
| | | | | | | | | | | | | | | | | Currently we always redirty an inode that was attempted to be written out synchronously but has been cleaned by an AIL pushed internall, which is rather bogus. Fix that by doing the i_update_core check early on and return 0 for it. Also include async calls for it, as doing any work for those is just as pointless. While we're at it also fix the sign for the EIO return in case of a filesystem shutdown, and fix the completely non-sensical locking around xfs_log_inode.

* xfs: fix xfs_mark_inode_dirty during umountChristoph Hellwig2011-08-31
| | | | | | | | | | | | | | | | | | | | | | | During umount we do not add a dirty inode to the lru and wait for it to become clean first, but force writeback of data and metadata with I_WILL_FREE set. Currently there is no way for XFS to detect that the inode has been redirtied for metadata operations, as we skip the mark_inode_dirty call during teardown. Fix this by setting i_update_core nanually in that case, so that the inode gets flushed during inode reclaim. Alternatively we could enable calling mark_inode_dirty for inodes in I_WILL_FREE state, and let the VFS dirty tracking handle this. I decided against this as we will get better I/O patterns from reclaim compared to the synchronous writeout in write_inode_now, and always marking the inode dirty in some way from xfs_mark_inode_dirty is a better safetly net in either case.

* xfs: fix tracing builds inside the source treeChristoph Hellwig2011-08-22
| | | | | | | | | | | | The code really requires the current source directory to be in the header search path. We already do this if building with an object tree separate from the source, but it needs to be added manually if building inside the source. The cflags addition for it accidentally got removed when collapsing the xfs directory structure.

| | | | | | | | | | | | Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the annoying subdirectories in the XFS source code. Besides the large amount of file rename the only changes are to the Makefile, a few files including headers with the subdirectory prefix, and the binary sysctl compat code that includes a header under fs/xfs/ from kernel/.

* xfs: set cursor in xfs_ail_splice() even when AIL was emptyAlex Elder2011-08-09
| | | | | | | | | | | | | | In xfs_ail_splice(), if a cursor is provided it is updated to point to the last item on the list being spliced into the AIL. But if the AIL was found to be empty, the cursor (if provided) is just initialized instead. There is no reason the empty AIL case needs to be treated any differently. And treating it the same way allows this code to be rearranged a bit, with a somewhat tidier result. Signed-off-by: Alex Elder <aelder@sgi.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the addition of file capabilities every write needs to read xattrs to check if we have any capabilities to clear. In Linux 3.0 Andi Kleen added a flag to cache the fact that we do not have any attributes on an inode. Make sure to already mark a file as not having any attributes when reading it from disk in case it doesn't even have an attribute fork. Based on an earlier patch from Andi Kleen.

The filesystems also don't need to check for a non-blocking RCU walk case in their acl_check() functions, because that is all handled at a VFS layer.

* | xfs: convert AIL cursors to use struct list_headDave Chinner2011-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The list of active AIL cursors uses a roll-your-own linked list with special casing for the AIL push cursor. Simplify this code by replacing the list with standard struct list_head lists, and use a separate list_head to track the active cursors. This allows us to treat the AIL push cursor as a generic cursor rather than as a special case, further simplifying the code. Further, fix the duplicate push cursor initialisation that the special case handling was hiding, and clean up all the comments around the active cursor list handling.
