[for-next-3.11][PATCH 0/9] tracing: A few more fixes

From: Steven Rostedt
Date: Wed Jul 24 2013 - 11:29:28 EST

Oleg is working on fixing a very tight race between opening a event file
and deleting that event at the same time (both must be done as root).

I also found a bug while testing Oleg's patches which has to do with
a race with kprobes using the function tracer.

There's also a deadlock fix that was introduced with the previous fixes.
