[PATCH 6/7] tracing: add trace name and id to event formats

[Steven Rostedt <rostedt@goodmis.org>]

[-- Attachment #1: 0006-tracing-add-trace-name-and-id-to-event-formats.patch --]
[-- Type: text/plain, Size: 1013 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

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.
