Subject: [PATCH v2 04/10] mm/damon/paddr: support damos_filter->allow
Date: Thu,  9 Jan 2025 09:51:20 -0800	[thread overview]
Message-ID: <20250109175126.57878-5-sj@kernel.org> (raw)
In-Reply-To: <20250109175126.57878-1-sj@kernel.org>

Respect damos_filter->allow from 'paddr', which is a DAMON operations
set implementation for the physical address space and supports a few
types of region-internal DAMOS filters (anon, memcg and young).  The
change is similar to that of the previous commit for core layer update.
