Subject: [PATCH rt-tests v2 13/14] ssdd: Add quiet command line option
Date: Fri, 5 Mar 2021 08:34:59 +0100 [thread overview]
Message-ID: <20210305073500.17926-14-dwagner@suse.de> (raw)
In-Reply-To: <20210305073500.17926-1-dwagner@suse.de>
The quiet option is useful for automated test setups where
only the final result of the run is interesting.
