Subject: [PATCH 02/12] mm/damon/core: remove debug messages
Date: Tue, 1 Sep 2026 22:47:35 -0700 [thread overview]
Message-ID: <20260902054747.99370-3-sj@kernel.org> (raw)
In-Reply-To: <20260902054747.99370-1-sj@kernel.org>
There are a few debug messages in DAMON core. Those have not really
been used in a meaningful way for the last few years, though. Remove
those.
