Subject: Return 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
