My plan is:

1) get libperf.so out for user tools to use.

2) Start hacking on code again :)

But I'll make sure that this will not be a burden on Google. There's no
reason that Google should be punished for using something that is
mainline, and using the proper ABIs. The code in ftrace is very flexible
and tools that use ftrace should still work even if we make internal
changes.

I'll work closely with you to make sure that Google's tools will always
work with future kernels.

No need to apologize, it's a very confusing situation.
