[RFC PATCH v2 0/7] cgroup-aware OOM killer

[Roman Gushchin <guro@fb.com>]

This patchset makes the OOM killer cgroup-aware.

Patches 1-3 are simple refactorings of the OOM killer code,
required to reuse the code in the memory controller.
Patches 4 & 5 are introducing new memcg settings:
oom_kill_all_tasks and oom_score_adj.
Patch 6 introduces the cgroup-aware OOM killer.
Patch 7 is docs update.

v1:

v2:
  - Reworked victim selection based on feedback
    from Michal Hocko, Vladimir Davydov and Johannes Weiner

  - Refined oom score calculations, suggested by Vladimir Davydov
  - Converted to a patchset
