6.6-stable review patch. If anyone has any objections, please let me know. ------------------ 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'.
