Subject: [PATCH 3/5] compiler-gcc: remove attribute support check for `__no_sanitize_thread__`
Date: Fri, 21 Oct 2022 13:59:54 +0200 [thread overview]
Message-ID: <20221021115956.9947-3-ojeda@kernel.org> (raw)
In-Reply-To: <20221021115956.9947-1-ojeda@kernel.org>
The attribute was added in GCC 5.1, which matches the minimum GCC version
supported by the kernel.
Therefore, remove the check.
