Subject: [RFC][PATCH 0/2] memcg: Require every task that uses an mm to migrate together


This is a follow up to my last patch of switching from mm->owner to
mm->memgcg and as it might be significant enough to break userspace.  I
am carefully not depending on this change.

Eric W. Biederman (2):
      memcg: Ensure every task that uses an mm is in the same memory cgroup
      memcgl: Remove dead code now that all tasks of an mm share a memcg
