Re: [PATCH 5/6] memcg: make mem_cgroup_reparent_charges non failing

[Michal Hocko]

This is an updated version of the patch. I have dropped
.__DEPRECATED_clear_css_refs in this one as it makes the best sense to
me. I didn't add Tejun's Reviewed-by because of this change. Could you
recheck, please?
