Subject[PATCH memcg RFC 0/3] memcg: prohibit unconditional exceeding the limit of dying tasks
Date
Dear Michal,
as you requested, I splited v4 patch version into 3 separate parts.
Let's discuss each of them.

Open questions/ToDo:

- Update patch descriptions (and add some comments)

- in part 2 aka "memcg: remove charge forcinig for dying tasks":
should we keep task_is_dying() in mem_cgroup_out_of_memory() ?

- in part 3 aka "memcg: handle memcg oom failures"
what is the best way to notify pagefault_out_of_memory() about
mem_cgroup_out_of_memory failure ?

- what is the best way to handle memcg failure doe to kmem limit,
it can trigger false global OOM

Vasily Averin (3):
mm: do not firce global OOM from inside dying tasks
memcg: remove charge forcinig for dying tasks
memcg: handle memcg oom failures
