On the current implementation, the "disable" keyword in "trace-events"
has different semantics, depending on the backend:
* nop : ignored (not a problem)
* simple : enables tracing, but sets dynamic state to disable
* ust : disables tracing (uses nop backend)
* dtrace : same as simple
Would it be possible to just use nop whenever the event is disabled in
trace-events? If you agree I can cook the patch, as it's pretty simple.
