From 84358536dc355a9c8978ee425f87e116186bed16 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 6 Apr 2017 16:00:39 -0700 Subject: xfs: actually report xattr extents via iomap 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. Signed-off-by: Darrick J.
