Subject: [RFC PATCH v3 36/37] mm/damon/sysfs: support write-type access sample filter
Date: Sun, 7 Dec 2025 22:29:40 -0800 [thread overview]
Message-ID: <20251208062943.68824-37-sj@kernel.org> (raw)
In-Reply-To: <20251208062943.68824-1-sj@kernel.org>
Allow users utilizing the write/read-only access sample results
filtering, by adding a new supported input for specifying the filter is
for that purpose.
