Weren't you talking something of that effect in memcg? Or was it
Michal? At any rate, I think you're missing the point why Li replied
that it's harmless. He, I think, meant that it doesn't make any
semantical difference to userland, so your reply saying that it's not
harmless listing the failure mode under memory pressure seemed
misleading, so I thought clarification was necessary. Probably my
(false?) memory of you talking about that contributed. Anyways, we
agree. Don't depend on it.

Thanks.
