X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=da2a061888883e067e8e649d086df35c92c760a7;p=linux.git Docs/admin-guide/mm/damon/usage: fix wrong example of DAMOS filter matching sysfs file 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.
