Reading discussion, I feel storing more data is difficult, too. I wonder, rather than collecting more data, rough calculation can help the situation. for example, (refault_disatance calculated in zone) * memcg_reclaim_ratio < memcg's active list If one of per-zone calc or per-memcg calc returns true, refault should be true. memcg_reclaim_ratio is the percentage of scan in a memcg against in a zone.
