Subject: [PATCH 15/16] tracing: show event name in trace for TRACE_EVENT created events
Date: Thu, 12 Mar 2009 22:37:19 -0400 [thread overview]
Message-ID: <20090313023828.029155950@goodmis.org> (raw)
In-Reply-To: 20090313023704.971438367@goodmis.org
[-- Attachment #1: 0015-tracing-show-event-name-in-trace-for-TRACE_EVENT-cr.patch --]
[-- Type: text/plain, Size: 1019 bytes --]
From: Steven Rostedt <srostedt@redhat.com>
Unlike TRACE_FORMAT() macros, the TRACE_EVENT() macros do not show
the event name in the trace file. Knowing the event type in the trace
output is very useful.
Instead of:
task swapper:0 [140] ==> ntpd:3308 [120]
We now have:
sched_switch: task swapper:0 [140] ==> ntpd:3308 [120]
