Subject: [PATCH v3, 0/4] mm, memcg: cgroup v1 and v2 tunable load/store tearing fixes

This patch series helps to prevent load/store tearing in
several cgroup knobs.

As kindly pointed out by Michal Hocko, we should add 
[WRITE|READ]_ONCE for all occurrences of memcg->oom_kill_disable,
memcg->swappiness and memcg->soft_limit.

v3:
- Add [WRITE|READ]_ONCE for all occurrences of
memcg->oom_kill_disable, memcg->swappiness and memcg->soft_limit
v2:
- Rephrase changelog
- Add [WRITE|READ]_ONCE for memcg->oom_kill_disable,
 memcg->swappiness, vm_swappiness and memcg->soft_limit
v1:
- Add [WRITE|READ]_ONCE for memcg->oom_group
