Sorry, I'll explain it better in the next release. This was just something 
that Ingo wanted cleaned up. He prefers the name "ftrace_turn_off". I 
really don't care what the name is, but the "atomic" part was something 
that had to go.

What's your preference fo a name of a function that should completely 
disable ftrace on anomaly detection?  Unfortunately, ftrace_stop, 
ftrace_disable, and ftrace_shutdown are already in use.
