Subject: [PATCH v3 15/15] kasan: don't run tests when KASAN is not enabled
Date: Thu, 14 Jan 2021 20:36:31 +0100 [thread overview]
Message-ID: <da60f1848b42dd04a4977e156715c8d0382a1ecd.1610652890.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1610652890.git.andreyknvl@google.com>
Don't run KASAN tests when it's disabled with kasan.mode=off to avoid
corrupting kernel memory.
