I wouldn't be opposed to fixing those names at all, but I think that
is out of the scope of this patch. Want to send one?
mem_cgroup_charge_anon() would be a good name, but then we should also
rename mem_cgroup_cache_charge() to mem_cgroup_charge_file() to match.
Or charge_private() vs. charge_shared()...
