Subject: [PATCH 1/3] kunit/fortify: Rename tests to use recommended conventions
Date: Mon, 29 Apr 2024 12:43:39 -0700
Message-Id: <20240429194342.2421639-1-keescook@chromium.org>
In-Reply-To: <20240429194019.work.664-kees@kernel.org>
References: <20240429194019.work.664-kees@kernel.org>
Precedence: bulk

The recommended conventions for KUnit tests is ${module}_test_${what}.
Adjust the fortify tests to match.
