Subject: [PATCH 0/3] page_counter cleanup and size reduction

The commit c6f53ed8f213a ("mm, memcg: cg2 memory{.swap,}.peak write
handlers") has accidently increased the size of struct page_counter.
This series rearrange the fields to reduce its size and also has some
cleanups.

Shakeel Butt (3):
  memcg: don't call propagate_protected_usage() for v1
  page_counter: track failcnt only for legacy cgroups
  page_counter: reduce struct page_counter size
