From: Steven Rostedt (Red Hat) Date: Wed, 12 Nov 2014 18:19:06 +0000 (-0500) Subject: tracing: Have branch tracer use trace_handle_return() helper function X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7d40f67165d9a4c9add5c0f7e599637a292bbfb2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
