Subject: [PATCH 4/8] mm/damon/sysfs: commit intervals tuning goal
Date: Mon, 3 Mar 2025 14:17:22 -0800 [thread overview]
Message-ID: <20250303221726.484227-5-sj@kernel.org> (raw)
In-Reply-To: <20250303221726.484227-1-sj@kernel.org>
Connect DAMON sysfs interface for sampling and aggregation intervals
auto-tuning with DAMON core API, so that users can really use the
feature using the sysfs files.
