Message-Id: <20210506131510.51488-3-frederic@kernel.org>
Date: Thu, 6 May 2021 15:15:09 +0200

Subject: [PATCH 2/3] torture: Add --configonly parameter for kvm.sh
Those who just want the resulting config file to generate for bare metal
don't need to wait for the build. Provide an option to only produce
the .config file.
