Subject: [GIT PULL] xfs: fixes for 4.17-rc4

Hi Linus,

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.  Let me know if there are any merge problems.

  xfs: don't fail when converting shortform attr to long form during ATTR_REPLACE (2018-04-17 19:10:15 -0700)

----------------------------------------------------------------
Changes since last update:
- 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.
