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