Changes from v1 as per comments from Steven/Daniel
- Use single tracepoint for irq/preempt/critical timings by introducing a trace type field to differentiate trace type in the same tracepoint.
Did you send out the right patches? This version still looks like the previous one in this regard. And wouldn't be the 'Histogram output' have only one file? Maybe I just understood something wrong here.
cheers, daniel
