Subject: [RFC PATCH v1.2 4/7] mm/damon/core: s/nr_accesses_to_accesses_bp/sample_count_to_bp/
Date: Tue, 7 Jul 2026 18:32:47 -0700 [thread overview]
Message-ID: <20260708013252.95888-5-sj@kernel.org> (raw)
In-Reply-To: <20260708013252.95888-1-sj@kernel.org>
damon_nr_accesses_to_accesses_bp() actually converts a positive sample
count to the ratio. Rename it to better describe what it really does
and not confusing for more general uses.
