[RFC PATCH 04/10] mm/damon/paddr: support damos_filter->pass

From: SeongJae Park
Date: Thu Dec 26 2024 - 17:15:49 EST


'paddr', a DAMON operations set implementation for the physical address
space supports a few types of DAMOS filters (anon, memcg and young), but
ignoring the ->pass field. Update the logic to support the behavior.
