From 7d40f67165d9a4c9add5c0f7e599637a292bbfb2 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 12 Nov 2014 13:19:06 -0500 Subject: [PATCH] tracing: Have branch tracer use trace_handle_return() helper function 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.
