[PATCH] tracing: create events only when configed

Lai Jiangshan
2009-05-22T09:43:41Z

There some unneeded events in debugfs/tracing/ftrace/ when the
corresponding CONFIG_XXXX=n.

And when CONFIG_ENABLE_EVENT_TRACING=n, various events
are still created.

Now when CONFIG_ENABLE_EVENT_TRACING=n, various events are
not created, trace_export.c is compiled only for creating
TRACEPOINTs.

[Impact:] cleanup
