Merge tag 'xfs-5.3-fixes-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Darrick Wong:
 "Here are a few more bug fixes that trickled in since the last pull.
  They've survived the usual xfstests runs and merge cleanly with this
  morning's master.

  I expect there to be one more pull request tomorrow for the fix to
  that quota related inode unlock bug that we were reviewing last night,
  but it will continue to soak in the testing machine for several more
  hours.

   - Fix missing compat ioctl handling for get/setlabel

   - Fix missing ioctl pointer sanitization on s390

   - Fix a page locking deadlock in the dedupe comparison code

   - Fix inadequate locking in reflink code w.r.t. concurrent directio

   - Fix broken error detection when breaking layouts"
