Subject: mm/damon/core.c: avoid unintentional filtering out of schemes
From: Hyeongtak Ji <hyeongtak.ji@xxxxxx>
commit 13b2a4b22e98ff80b888a160a2acd92d81b05925 upstream.
The function '__damos_filter_out()' causes DAMON to always filter out
schemes whose filter type is anon or memcg if its matching value is set
to false.
This commit addresses the issue by ensuring that '__damos_filter_out()'
no longer applies to filters whose type is 'anon' or 'memcg'.
