Subject: [rt-tests v2 v2 19/20] cyclictest: Remove max cpus used verbose information
Date: Fri, 18 Dec 2020 17:18:42 +0100 [thread overview]
Message-ID: <20201218161843.1764-20-dwagner@suse.de> (raw)
In-Reply-To: <20201218161843.1764-1-dwagner@suse.de>
Since we always print the thread placement in verbose mode now, there
is no need to print the max_cpus anymore. With the last of max_cpus
gone, we can also remove the sysconf() call.
