[PATCH 0/3] Introduce acctmem

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

As a step towards shrinking struct page, we need to remove all references
to page->memcg_data.  The model I'm working towards is described at
https://kernelnewbies.org/MatthewWilcox/Memdescs

In working on this series, I'm dissatisfied with how much I've assumed
that every page belongs to a folio.  There will need to be more changes
in order to split struct acctmem from struct folio in the future.
The first two patches take some steps in that direction, but I'm not
going to do any more than that in this series.

Matthew Wilcox (Oracle) (3):
  mm: Opencode split_page_memcg() in __split_huge_page()
  mm: Simplify split_page_memcg()
  mm: Introduce acctmem
