Thanks for addressing my comments.
I see that patch 8 was updated to address David's comments.  I will also
review patch 8 later.

I am again requesting that someone with more cgroup experience comment on
this patch.  I do not have enough experience to determine if the code to
not reparent/zombie cgroup is correct.

For now,
Acked-by: Mike Kravetz <mike.kravetz@oracle.com>
while waiting for cgroup comments.
