I'm not sure why this was dropped since it's vitally needed for any sane 
userspace oom handler to be effective.

It was dropped because the other memcg developers disagreed with it.

It was acked-by Michal.

I have already explained why I have acked it. I will not repeat
it here again. I have also proposed an alternative solution
(https://lkml.org/lkml/2013/12/12/174) which IMO is more viable because
it handles both user/kernel memcg OOM consistently. This patch still has
to be discussed because of other Johannes concerns. I plan to repost it
in a near future.
