- 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.

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"
