Maybe this is a mismatch in vocabulary what you mean by the verb "limit". But I don't see in the patchset that the offending pages would be allocated with GFP_ACCOUNT. So the result is that the pages are accounted (you can view the amount in memory.stat) but they are not subject to memcg limits. Is that what you intend? Regards, Michal
