Date: Mon, 9 Jun 2014 22:02:16 +0200 From: Jiri Olsa <jolsa@...nel.org> To: Ingo Molnar <mingo@...nel.org> Cc: linux-kernel@...r.kernel.org, "Steven Rostedt (Red Hat)" <rostedt@...dmis.org>, Jiri Olsa <jolsa@...nel.org> Subject: [PATCH 01/15] tools lib traceevent: Add flag to not load event plugins From: "Steven Rostedt (Red Hat)" <rostedt@...dmis.org> Add a flag to pevent that will let the callers be able to set it and keep the system, and perhaps even normal plugins from being loaded. This is useful when plugins might hide certain information and seeing the raw events shows what may be going on.
