I have to see what workflows it will affect first. This is what I was afraid of. The tracers irqsoff and preemptoff do not get reset if you echo the tracer name into the current_tracer. This makes different tracers inconsistent. All tracers must act the same. So, it's a no go for this patch, at least in its current form. -- Steve
