Subject: [PATCH 8/9] mm/vmscan: restore active/inactive ratio for anonymous LRU
Date: Tue, 11 Feb 2020 15:19:52 +0900	[thread overview]
Message-ID: <1581401993-20041-9-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1581401993-20041-1-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.
