I know these requests usually come from Darrick, and we had intended
that they would come that route.  Between the holidays and various
things which Darrick needed to work on, he asked if I could send the
pull request directly.  There weren't any other iomap patches pending
for this release, which probably also played a role.

There is a conflict between this tree and the nvdimm tree.  We've done
our best to make the resolution easy for you with the last patch in this
series ("Inline __iomap_zero_iter into its caller").  If you'd rather just
resolve the entire conflict yourself, feel free to drop that last patch.

The resolution Stephen has been carrying is here:

  iomap: Inline __iomap_zero_iter into its caller (2021-12-21 13:51:08 -0500)

----------------------------------------------------------------
Convert xfs/iomap to use folios

This should be all that is needed for XFS to use large folios.
There is no code in this pull request to create large folios, but
no additional changes should be needed to XFS or iomap once they
are created.
