memcg swap doesn't work in mmotm-2014-07-09-17-08?

Hi,

It seems that when a process in some memcg tries to allocate more than
memcg.limit_in_bytes, oom happens instead of swaping out in
mmotm-2014-07-09-17-08 (memcg.memsw.limit_in_bytes is large enough).
It does work in v3.16-rc3, so I think latest patches changed something.
I'm not familiar with memcg internally, so no idea about what caused it.
Could you see the problem?
