Subject: [PATCH v4 0/2] mm, memcg: memory.{low,min} reclaim fix & cleanup

This series contains a fix for a edge case in my earlier protection
calculation patches, and a patch to make the area overall a little more
robust to hopefully help avoid this in future.

Changes in v4:

- Fix premature OOM when checking protection on root memcg. Thanks
  Naresh and Michal for helping debug.

Chris Down (1):
  mm, memcg: Decouple e{low,min} state mutations from protection checks

Yafang Shao (1):
  mm, memcg: Avoid stale protection values when cgroup is above
    protection
