Linus,
Oleg is working on fixing a very tight race between opening an 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.
