Subject: [for-next][PATCH 24/25] tracing: Rename tracing_reset() to tracing_reset_cpu()
Date: Thu, 05 Sep 2019 11:43:22 -0400 [thread overview]
Message-ID: <20190905154344.021926536@goodmis.org> (raw)
In-Reply-To: 20190905154258.573706229@goodmis.org
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
The name tracing_reset() was a misnomer, as it really only reset a single
CPU buffer. Rename it to tracing_reset_cpu() and also make it static and
remove the prototype from trace.h, as it is only used in a single function.
