Subject: [PATCH v5 09/10] mm/vmscan: restore active/inactive ratio for anonymous LRU
Date: Fri, 3 Apr 2020 14:40:47 +0900 [thread overview]
Message-ID: <1585892447-32059-10-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1585892447-32059-1-git-send-email-iamjoonsoo.kim@lge.com>
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.
