Looks like this is entirely perf based and does not interact with

It makes more sense to go through tip than the tracing tree.

well, all of earlier series were based on ftrace only,
but I was given convincing enough arguments that
perf_even_open+ioctl is a better interface :)
Ok. will rebase on tip in the next version.

That's fine. If this proves useful, I'll probably add the interface
back to ftrace as well.
