stable inclusion from stable-v6.6.3 commit 1777bb5c740d6d8837dbae61b4694ef90f363221 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP

--------------------------------
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'.
