Subject: mm/vmscan: make the annotations of refaults code at the right place
Date: Sat, 13 Aug 2022 08:07:58 +0000
After patch "mm/workingset: prepare the workingset detection
infrastructure for anon LRU", we can handle the refaults of anonymous
pages too. So the annotations of refaults should cover both of anonymous
pages and file pages.
