Pull xfs fixes from Darrick Wong:
 "Here are a few more bug fixes for xfs for 4.17-rc4. Most of them are
  fixes for bad behavior.

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

  Summary:

   - Enhance inode fork verifiers to prevent loading of corrupted
     metadata.

   - Fix a crash when we try to convert extents format inodes to btree
     format, we run out of space, but forget to revert the in-core state
     changes.

   - Fix file size checks when doing INSERT_RANGE that could cause files
     to end up negative size if there previously was an extent mapped at
     s_maxbytes.

   - Fix a bug when doing a remove-then-add ATTR_REPLACE xattr update
     where we forget to clear ATTR_REPLACE after the remove, which
     causes the attr to be lost and the fs to shut down due to (what it
     thinks is) inconsistent in-core state"
