Merge tag 'xfs-4.18-merge-10' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Browse Source 
Pull more xfs updates from Darrick Wong:
 "Here's the second round of patches for XFS for 4.18. Most of the
  commits are small cleanups, bug fixes, and continued strengthening of
  metadata verifiers; the bulk of the diff is the conversion of the
  fs/xfs/ tree to use SPDX tags.

  This series has been run through a full xfstests run over the weekend
  and through a quick xfstests run against this morning's master, with
  no major failures reported.

  Summary:

   - Strengthen metadata checking to avoid ASSERTing on bad disk
     contents

   - Validate btree records that are being retrieved for clients

   - Strengthen root inode verification

   - Convert license blurbs to SPDX tags

   - Enable changing DAX flag on directories

   - Fix some writeback deadlocks in reflink

   - Refactor out some old xfs helpers

   - Move type verifiers to a separate file

   - Fix some fuzzer crashes

   - Various other bug fixes"
