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.
