Add kernel-style events for sched_trace_XXX() functionswip-tracepoints
Enable kernel-style events (tracepoint) for Litmus. Litmus events
trace the same functions as the sched_trace_XXX(), but can be
enabled independently.
So, why another tracing infrastructure then:
- Litmus tracepoints can be recorded and analyzed together (single
time reference) with all other kernel tracing events (e.g.,
sched:sched_switch, etc.). It's easier to correlate the effects
of kernel events on litmus tasks.
- It enables a quick way to visualize and process schedule traces
using trace-cmd utility and kernelshark visualizer.
Kernelshark lacks unit-trace's schedule-correctness checks, but
it enables a fast view of schedule traces and it has several
filtering options (for all kernel events, not only Litmus').
