SubjectReturn value of print_graph_prologue
Hi,

I got confused about the return value of print_graph_prologue. See:

805 /* Latency format */
806 if (trace_flags & TRACE_ITER_LATENCY_FMT) {
807 ret = print_graph_lat_fmt(s, ent);
808 if (ret == TRACE_TYPE_PARTIAL_LINE)
809 return TRACE_TYPE_PARTIAL_LINE;
810 }
811
812 return 0;
813 }

But we have defined TRACE_TYPE_PARTIAL_LINE = 0. So there's
no difference between success and failure?

Should it be TRACE_TYPE_HANDLED ?

Regards,
Wenji
