tools lib traceevent: Add retrieval of preempt count and latency flags Add a way to retrieve the preempt count as well as the latency flags from a pevent_record. int pevent_data_preempt_count(pevent, record); returns the preempt count of a record. int pevent_data_flags(pevent, record); returns the latency flags for a record.
