Subject[PATCH 00/21] iomap/xfs folio patches
Date
This patchset converts XFS & iomap to use folios, and gets them to
a state where they can handle multi-page folios. I don't anticipate
needing to touch XFS again until we're at the point where we want to
convert the aops to be type-safe. The patches apply to both current
Linus head and next-20211101. It completes an xfstests run with no
unexpected failures. Most of these patches have been posted before and
I've retained acks/reviews where I thought them reasonable. Some are new.

I'd really like a better name than 'mapping_set_large_folios()'.
mapping_set_multi_page_folios() seems a bit long. mapping_set_mpf()
is a bit obscure.

Jens, I'd really like your ack on patches 2 & 3; I know we discussed
them before.
