And now, in cgroup tree, pre_destroy() failure cause WARNING. Just to clarify, I'm not intending to ->pre_destroy() per-se but the retry behavior of it, so ->pre_destroy() will be converted to return void and called once on rmdir and rmdir will proceed no matter what. Also, with the deprecated behavior flag set, pre_destroy() doesn't trigger the warning message. Other than that, if memcg people are fine with the change, I'll be happy to route the changes through cgroup/for-3.5 and stack rmdir simplification patches on top.
