[PATCH v5 09/10] mm/vmscan: restore active/inactive ratio for anonymous LRU

[js1304]

From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx>

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.
