Merge tag 'xfs-4.13-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull XFS fixes from Darrick Wong:
"Largely debugging and regression fixes.
- 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"
* tag 'xfs-4.13-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
vfs: in iomap seek_{hole,data}, return -ENXIO for negative offsets
Revert "xfs: grab dquots without taking the ilock"
xfs: assert locking precondition in xfs_readlink_bmap_ilocked
xfs: assert locking precondŃ–tion in xfs_attr_list_int_ilocked
xfs: fixup xfs_attr_get_ilocked
