Subject: [GIT PULL] iomap folio conversion for 5.17

Hi Darrick,

Would you like to pull the folio changes from my git tree?
They are generally as posted previously, with minor tweaks to match
upstream changes.  They do not introduce any new xfstests problems
in my testing.

The following changes since commit d58071a8a76d779eedab38033ae4c821c30295a5:

  Linux 5.16-rc3 (2021-11-28 14:09:19 -0800)

are available in the Git repository at:

  xfs: Support large folios (2021-11-29 08:30:52 -0500)

----------------------------------------------------------------
Convert fs/iomap to use folios

These patches prepare XFS to use large folios to cache files.
There are some preliminary patches to add folio interfaces to the
block layer & buffer layer, then all the iomap functions are
converted to use folios instead of pages.

----------------------------------------------------------------
Matthew Wilcox (Oracle) (24):
      block: Add bio_add_folio()
      block: Add bio_for_each_folio_all()
      fs/buffer: Convert __block_write_begin_int() to take a folio
      iomap: Convert to_iomap_page to take a folio
      iomap: Convert iomap_page_create to take a folio
      iomap: Convert iomap_page_release to take a folio
      iomap: Convert iomap_releasepage to use a folio
      iomap: Add iomap_invalidate_folio
      iomap: Pass the iomap_page into iomap_set_range_uptodate

      iomap: Use folio offsets instead of page offsets
      iomap: Convert iomap_read_inline_data to take a folio
      iomap: Convert readahead and readpage to use a folio
      iomap: Convert iomap_page_mkwrite to use a folio
      iomap: Convert __iomap_zero_iter to use a folio
      iomap: Convert iomap_write_begin() and iomap_write_end() to folios
