It says 3.2.0-next-20120119-sasha #128

I notice that, unlike Linus's git, this linux-next still has mm-isolate-pages-for-immediate-reclaim-on-their-own-lru.patch in.
I think that was well capable of oopsing in mem_cgroup_lru_del_list(), since it didn't always know which lru a page belongs to.
I'm going to be optimistic and assume that was the cause.
