From fe4549b1d6aca7cffb4ab5010f7918263a6b1058 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Fri, 3 May 2024 11:03:14 -0700 Subject: [PATCH] Docs/admin-guide/mm/damon/usage: fix wrong example of DAMOS filter matching sysfs file commit da2a061888883e067e8e649d086df35c92c760a7 upstream. The example usage of DAMOS filter sysfs files, specifically the part of 'matching' file writing for memcg type filter, is wrong. The intention is to exclude pages of a memcg that already getting enough care from a given scheme, but the example is setting the filter to apply the scheme to only the pages of the memcg. Fix it.
