Hello, KAMEZAWA.
Thanks a lot for doing this.

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.
Thanks.
