Merge tag 'xfs-4.15-fixes-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Darrick Wong:
 "Here are some bug fixes for 4.15-rc2.

   - fix memory leaks that appeared after removing ifork inline data
     buffer

   - recover deferred rmap update log items in correct order

   - fix memory leaks when buffer construction fails

   - fix memory leaks when bmbt is corrupt

   - fix some uninitialized variables and math problems in the quota
     scrubber

   - add some omitted attribution tags on the log replay commit

   - fix some UBSAN complaints about integer overflows with large sparse
     files

   - implement an effective inode mode check in online fsck

   - fix log's inability to retry quota item writeout due to transient
     errors"

* tag 'xfs-4.15-fixes-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
