[GIT PULL] xfs: 4.19 merge, part 1

[Darrick J. Wong]

Hi Linus,

This is the first part of the XFS changes for 4.19.  Christoph and
Andreas coordinated some refactoring work on the iomap code in
preparation for removing buffer heads from XFS and porting gfs2 to
iomap.  I'm sending this small pull request ahead of the main XFS merge
to avoid holding up gfs2 unnecessarily.
