Well, it matters what you your definition of "safe" is ;-)

The new change prevents the ring buffer from having anything written to it,
where as the old change didn't disable everything.

Good point. How about I add a tracer_tracing_disable() and
tracer_tracing_enable() that is not an on off switch and uses:
ring_buffer_disable/enable() that decrements/increments disabling of the
ring buffer?

That way it keeps the same semantics.
