Reason being, there's no way for libtraceevent to know which this is. We could even have a mixture of these in the trace. Instead of an option, we can add a new trigger: stacktrace_rel that will do a relative stack trace. And the event can be kernel_stack_rel Then it can be enabled via: echo 'stacktrace_rel if prev_state & 3' > events/sched/sched_switch/trigger -- Steve
