[v13b,00/18] Convert memcg to folios

Message

Matthew Wilcox July 12, 2021, 7:45 p.m. UTC

This is the part of the v13 patch series which deals with converting
(most of) the memcg interfaces to work with folios instead of pages.
A few interfaces are not changed due to having exclusively or many
users which are not going to be converted to folios soon.  Eventually,
all memcg interfaces should be converted to folios as all accounting of
memory is done on and with the head page.

A few of these patches ran into trouble with the build bots, and those
problems have been corrected.  I imagine that posting this as a patch
series independently of v13a will cause the build bots to report errors
as I don't know how to tell them that this series depends on that series.
