Subject: [PATCH] tracing: Remove obsolete sched_switch tracer selftest
Date: Fri, 8 Sep 2017 23:55:17 -0700 [thread overview]
Message-ID: <20170909065517.22262-1-joelaf@google.com> (raw)
Since commit 87d80de2800d087ea833cb79bc13f85ff34ed49f ("tracing: Remove
obsolete sched_switch tracer"), the sched_switch tracer selftest is no longer
used. This patch removes the same.
