Subject: [PATCH 0/9] [GIT PULL] tracing: fixes


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.

Please pull the latest trace-fixes-3.11-rc2 tree, which can be found at:
