Subject: [RFC PATCH 7/9] selftests/damon/sysfs_memcg_path_leak: fail only for real DAMON leak
Date: Sat, 12 Sep 2026 13:08:08 -0700 [thread overview]
Message-ID: <20260912200814.145612-8-sj@kernel.org> (raw)
In-Reply-To: <20260912200814.145612-1-sj@kernel.org>
The selftest can fail for any leak if it happens while the test is
running. Remove the false positive test failures by further checking if
the expected leaking function is called out on the report.
Signed-off-by: SJ Park <sj@kernel.org>
