Subject: Ftrace doesn't work anymore on latest tip

Hi,

I tried to launch the function tracer with the latest -tip.
With DYNAMIC_FTRACE (I just tried one time), I set "function" to
current_trace and it blocks during writing. I can't
even switch to another console.
Without DYNAMIC_FTRACE I can set the tracer to function but it doesn't
produce any trace, even on trace or tracing_pipe.

My config is in attachment.
I will try some revert...or some other tracers.
