Subject: [PATCH rt-tests v3 32/33] ssdd: Add quiet command line option
Date: Sat, 20 Mar 2021 19:38:28 +0100
Message-ID: <20210320183829.1318-33-dwagner@suse.de> (raw)
In-Reply-To: <20210320183829.1318-1-dwagner@suse.de>

The quiet option is useful for automated test setups where
only the final result of the run is interesting.
