Subject: [PATCH 12/19] mm/damon/core: set samples in apply_probes() if probe weights are set
Date: Fri, 10 Jul 2026 06:46:41 -0700 [thread overview]
Message-ID: <20260710134651.18084-13-sj@kernel.org> (raw)
In-Reply-To: <20260710134651.18084-1-sj@kernel.org>
When probe weights are set, the prepare_access_checks() ops callback is
not invoked, so sampling addresses of regions are unset. Ask
apply_probes() to set those together in the case.
Signed-off-by: SJ Park <sj@kernel.org>
