Subject: [RFC][PATCH 0/2] memcg: use ID instead of pointer in page_cgroup ,
 retry.


This is a reviced series of use ID.
Restart from RFC.

[1/2] implementation of special ID lookup
[2/2] use ID in mm/memcontrol.c

People may say use css_lookup() and don't add a special routine but
I can't believw css_lookup() can give us enough speed at every page LRU handling
if the number of cgroup is big. I think this patch itself is enough simple...
but I admit this will make mem_cgroup more complex. Hmm.

Thanks,
-Kame
