The review status is: [1/3] mm, memcg: proportional memory.{low,min} reclaim Acked-by: Johannes Reviewed-by: Roman [2/3] mm, memcg: make memory.emin the baseline for utilisation determination Acked-by: Johannes [3/3] mm, memcg: make scan aggression always exclude protection Reviewed-by: Roman I do have a note here that mhocko intended to take a closer look but I don't recall whether that happened. I could a) say what the hell and merge them or b) sit on them for another cycle or c) drop them and ask Chris for a resend so we can start again.
