From abc74dca458bb81b81ad40efecda69a6fa28fd3c Mon Sep 17 00:00:00 2001 From: John Kacur Date: Sat, 14 Sep 2019 04:57:35 +0200 Subject: [PATCH] rt-tests: cyclictest.8: Remove invalid tracing options from the manpage Most tracing options have been removed from cyclictest since the user can now use trace-cmd together with cyclictest to get the same functionality. Update the manpage to reflect this.
