As Masami has pointed out, the prefix trace_ should not be used. Also having trace_latency_ and latency_trace_ is kind of confusing. What about {start|stop}_latency_timing()? It would match the existing {start|stop}_critical_timing(). Or is it too close and it leads to confusion?
Another idea is {start|stop}_latency_preempt(). This matches the trace_latency_preempt_enable() function.
