Cover letter [PATCH 0/3] Make workingset detection logic memcg aware
Hi,
Currently, workingset detection logic is not memcg aware - inactive_age is maintained per zone. As a result, if memory cgroups are used, refaulted file pages are activated randomly. This patch set makes inactive_age per lruvec so that workingset detection will work correctly for memory cgroup reclaim.
Thanks,
Vladimir Davydov (3):
