-Subject: [PATCH 2/9] [PATCH 2/9] xfs: fix xfs_mark_inode_dirty during umount
-
-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.

-
-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.

-Subject: [PATCH 4/9] [PATCH 4/9] xfs: dont serialise direct IO reads on page
-	cache
-
-There is no need to grab the i_mutex of the IO lock in exclusive
-mode if we don't need to invalidate the page cache. Taking these
-locks on every direct IO effective serialises them as taking the IO
-lock in exclusive mode has to wait for all shared holders to drop
-the lock. That only happens when IO is complete, so effective it
-prevents dispatch of concurrent direct IO reads to the same inode.
-
-Fix this by taking the IO lock shared to check the page cache state,
-and only then drop it and take the IO lock exclusively if there is
-work to be done. Hence for the normal direct IO case, no exclusive
-locking will occur.

-
-An attribute of inode can be fetched via xfs_vn_getattr() in XFS.
-Currently it returns EIO, not negative value, when it failed.  As a
-result, the system call returns not negative value even though an
-error occured. The stat(2), ls and mv commands cannot handle this
-error and do not work correctly.
