Subject: [PATCH v2 1/2] Fix invalid use of NULL in epoll_pwait2(2) test
Date: Wed, 31 May 2023 22:44:22 +0200 [thread overview]
Message-ID: <20230531204422.18052-1-alx@kernel.org> (raw)
In-Reply-To: <6c399f6b-6e89-17c4-2a56-1219a1b86448@linaro.org>
epoll_pwait2(2)'s second argument should be nonnull. We're going to add
__nonnull to the prototype, so let's fix the test accordingly. We can
use a dummy variable to avoid passing NULL.
