    Subject[for-next][PATCH 28/32] tracing: Remove function_trace_stop and HAVE_FUNCTION_TRACE_MCOUNT_TEST
    From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

    All users of function_trace_stop and HAVE_FUNCTION_TRACE_MCOUNT_TEST have
    been removed. We can safely remove them from the kernel.
