[GIT PULL] xfs: updates for 4.13, part 2

[Darrick J. Wong]

Hi Linus,

Here are some more changes for you for 4.13; they're largely debugging
and regression fixes.  The branch merges against this afternoon's HEAD
without issue; a quick overnight xfstests run against yesterday's HEAD
came out cleanly.  Let me know if there are any problems.

  vfs: in iomap seek_{hole,data}, return -ENXIO for negative offsets (2017-07-13 14:55:05 -0700)

----------------------------------------------------------------
Changes since last update:
- Add some locking assertions for the _ilock helpers.
- Revert the XFS_QMOPT_NOLOCK patch; after discussion with hch the
  online fsck patch that would have needed it has been redesigned and
  no longer needs it.
- Fix behavioral regression of SEEK_HOLE/DATA with negative offsets to match
  4.12-era XFS behavior.

----------------------------------------------------------------
