[RFC PATCH v2 04/10] mm/damon/paddr: support damos_filter->pass

[SeongJae Park <sj@kernel.org>]

'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.
