While testing memcg, I feel that only I and Balbir and Nishimura are heavy
testers of memcg in mmotm. Because Nishimura's test is very good, I think
we could get good quality to some extent.
 
Then, I think it's time to move to -rc for getting wider testers.

But Balbir, soft-limit is a difficult thing. plz keep checking.

plz don't call it as resource counter scalability patch ;)
It just skips resoruce_counter, resource_counter itself is still slow.
root-cgroup-memcg-scalability patch is good name.

I'll post other-cgroup-memcg-scalability patch series when it seems ready.
It's what I need but not for 2.6.32.

Thanks,
