Subject: xfs: actually report xattr extents via iomap
From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>
commit 84358536dc355a9c8978ee425f87e116186bed16 upstream.
Apparently FIEMAP for xattrs has been broken since we switched to
the iomap backend because of an incorrect check for xattr presence.
Also fix the broken locking.
