I hate trips where my email box becomes filled. I skip over a lot of 
emails that I should not have.

I think I added a way to do this. Hmm, I think it was in -rt that I added 
it, and have not gotten around to sending you the updates.

Yes, we need an easy way to disable the tracer. I think we have 
ftrace_disable() function. Perhaps that only disables tracing that checks 
the tracing_disabled variable.

Anyway, I made sure the new ring_buffer code has an easy way to disable 
it.
