Subject: Docs/admin-guide/mm/damon/usage: fix wrong example of DAMOS filter matching sysfs file
Date: Fri, 3 May 2024 11:03:14 -0700
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.
