From: Hugh Dickins <hughd@xxxxxxxxxx> Subject: 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.
