From a7c3196c79051f9e1a498f5be8fe6870bde5e55d Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Mon, 2 Jun 2014 23:20:13 -0400 Subject: [PATCH] tools lib traceevent: Add flag to not load event plugins 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.
