Subject: [PATCH 2/6] selftests/damon/huge_count_read_write: remove unnecessary debugging message
Date: Mon, 28 Oct 2024 16:30:54 -0700 [thread overview]
Message-ID: <20241028233058.283381-3-sj@kernel.org> (raw)
In-Reply-To: <20241028233058.283381-1-sj@kernel.org>
The program prints expected errors from write/read of the files with
invalid huge count, for only debugging purpose. It is only making the
output noisy. Remove those.
Fixes: b4a002889d24 ("selftests/damon: test debugfs file reads/writes with huge count")
Signed-off-by: SeongJae Park <sj@kernel.org>
