[for-next][PATCH 10/18] tracing: Have branch tracer use trace_handle_return() helper function
From: Steven Rostedt
Date: Wed Nov 19 2014 - 18:31:14 EST
From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>
The branch tracer should not be checking the trace_seq_printf() return value
as that will soon be void. There's a new trace_handle_return() helper function
that will return TRACE_TYPE_PARTIAL_LINE if the trace_seq overflowed
and TRACE_TYPE_HANDLED otherwise.
