SubjectRe: [PATCH mm v5 0/9] memcg: accounting for objects allocated by mkdir, cgroup

Yes, I do not think we have concluded this to be really necessary. IIRC
Roman would like to see lingering cgroups addressed in not-so-distant
future (http://lkml.kernel.org/r/Ypd2DW7id4M3KJJW@carbon) and we already
have a limit for the number of cgroups in the tree. So why should we
chase after allocations that correspond the cgroups and somehow try to
cap their number via the memory consumption. This looks like something
that will get out of sync eventually and it also doesn't seem like the
best control to me (comparing to an explicit limit to prevent runaways).
