[v14c,00/39] Memory folios: Pagecache edition

Message

Matthew Wilcox July 15, 2021, 7:59 p.m. UTC

This patch series is for human review.  The bots are going to complain
because it depends on the previous 50 folio patches which are now quite
well reviewed (thanks!)  It's almost identical to patches 51-89 of
folio v14 (added a few R-b tags and a couple of minor build fixes)

This set of patches are everything that needs to be done before I can
convert iomap to use folios.  It's probably also all or most of what
needs to be done before other filesystems can be converted to use folios.
So getting this into v5.15 will enable a lot of other work to start.
