    Subject[PATCH v2 8/9] mm/vmscan: restore active/inactive ratio for anonymous LRU
    Date
    From: Joonsoo Kim <iamjoonsoo.kim@lge.com>

    Now, workingset detection is implemented for anonymous LRU.
    We don't have to worry about the misfound for workingset due to
    the ratio of active/inactive. Let's restore the ratio.
