[PATCH for v5.8 2/3] mm/swap: fix for "mm: workingset: age nonresident information alongside anonymous pages"

From: js1304
Date: Tue Jun 16 2020 - 02:17:17 EST


From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx>

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".
