Subject: [PATCH 2/2] kcsan: test: Add a .kunitconfig to run KCSAN tests
Date: Wed, 18 May 2022 15:32:32 +0800	[thread overview]
Message-ID: <20220518073232.526443-2-davidgow@google.com> (raw)
In-Reply-To: <20220518073232.526443-1-davidgow@google.com>

Add a .kunitconfig file, which provides a default, working config for
running the KCSAN tests. Note that it needs to run on an SMP machine, so
to run under kunit_tool, the x86_64-smp qemu-based setup should be used:
./tools/testing/kunit/kunit.py run --arch=x86_64-smp --kunitconfig=kernel/kcsan
