Subject: [PATCH for v5.8 2/3] mm/swap: fix for "mm: workingset: age nonresident information alongside anonymous pages"
Date: Tue, 16 Jun 2020 15:16:43 +0900 [thread overview]
Message-ID: <1592288204-27734-3-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1592288204-27734-1-git-send-email-iamjoonsoo.kim@lge.com>
From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Non-file-lru page could also be activated in mark_page_accessed()
and we need to count this activation for nonresident_age.
Note that it's better for this patch to be squashed into the patch
"mm: workingset: age nonresident information alongside anonymous pages".
