tracing: New macro to set up initial event flags value
This introduces the new TRACE_EVENT_FLAGS() macro in order to set up initial event flags value. This macro must simply follow the definition of a trace event and take the event name and the flag value as parameters: TRACE_EVENT(my_event, ..... .... ); TRACE_EVENT_FLAGS(my_event, 1) This will set up 1 as the initial my_event->flags value.
