Subject: [PATCH 4/7] mm/damon/paddr: implement DAMOS filter type YOUNG
Date: Fri, 26 Apr 2024 12:52:43 -0700 [thread overview]
Message-ID: <20240426195247.100306-5-sj@kernel.org> (raw)
In-Reply-To: <20240426195247.100306-1-sj@kernel.org>
DAMOS filter of type YOUNG is defined, but not yet implemented by any
DAMON operations set. Add the implementation on 'paddr', the DAMON
operations set for the physical address space.
