Subject[PATCH 00/14] [GIT PULL] tracing: fixes, clean ups and optimizations

Linus,

This contains fixes, optimizations and some clean ups

Some of the fixes need to go back to 3.10. They are minor, and deal mostly
with incorrect ref counting in accessing event files.

There was a couple of optimizations that should have perf perform a bit
better when accessing trace events.

And some various clean ups. Some of the clean ups are necessary to help
in a fix to a theoretical race between opening a event file and
deleting that event. That fix isn't there yet, we are still working on
a clean solution.

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

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git
trace-3.11-rc2
