From d3629af59f41a108d6c552f1dcba31281fb8e6bf Mon Sep 17 00:00:00 2001 From: Yang Yang Date: Sat, 13 Aug 2022 08:07:58 +0000 Subject: mm/vmscan: make the annotations of refaults code at the right place 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.
