From 2d9112fa0ebef0ed597b6afe6b9c2354ae97f067 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 4 May 2021 18:38:00 -0700 Subject: [PATCH] mm: /proc/sys/vm/stat_refresh stop checking monotonic numa stats All of the VM NUMA stats are event counts, incremented never decremented: it is not very useful for vmstat_refresh() to check them throughout their first aeon, then warn on them throughout their next.
