[PATCH] mm/damon/core.c: avoid unintentional filtering out of schemes

From: Hyeongtak Ji
Date: Fri Nov 10 2023 - 13:07:10 EST


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'.
