Subject: [PATCH v7 6/6] mm/vmscan: restore active/inactive ratio for anonymous LRU
Date: Thu, 23 Jul 2020 16:49:20 +0900 [thread overview]
Message-ID: <1595490560-15117-7-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1595490560-15117-1-git-send-email-iamjoonsoo.kim@lge.com>
From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Now that workingset detection is implemented for anonymous LRU, we don't
need large inactive list to allow detecting frequently accessed pages
before they are reclaimed, anymore. This effectively reverts the temporary
measure put in by commit "mm/vmscan: make active/inactive ratio as 1:1 for
anon lru".
