Add prototype declaration of function to header file include/linux/ftrace.h because it is used by more than one file.
This eliminates the following warning in kernel/trace/ftrace.c: kernel/trace/ftrace.c:4914:5: warning: no previous prototype for ‘ftrace_graph_entry_stub’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.khe...@gmail.com> Reviewed-by: Josh Triplett <j...@joshtriplett.org> --- include/linux/ftrace.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/include/linux/ftrace.h b/include/linux/ftrace.h index 68ea184..da1c31f 100644 --- a/include/linux/ftrace.h +++ b/include/linux/ftrace.h @@ -672,6 +672,8 @@ struct ftrace_graph_ret { typedef void (*trace_func_graph_ret_t)(struct ftrace_graph_ret *); /* return */ typedef int (*trace_func_graph_ent_t)(struct ftrace_graph_ent *); /* entry */ +int ftrace_graph_entry_stub(struct ftrace_graph_ent *trace); + #ifdef CONFIG_FUNCTION_GRAPH_TRACER /* for init task */ -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
