From c5e4e19271edfdf1abd4184933d40d646da6a091 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Mon, 2 Mar 2009 15:10:02 -0500 Subject: [PATCH] tracing: add trace name and id to event formats To be able to identify the trace in the binary format output, the id of the trace event (which is dynamically assigned) must also be listed. This patch adds the name of the trace point as well as the id assigned.
