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.

[chris@chrisdown.name: commit log above]

Changes since v1:
work around the stale protection values in mem_cgroup_protection(), rather
than in mem_cgroup_protected().

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
