Mark functions as static in kernel/trace/trace.c because they are not used outside this file.
This eliminates the following warning in kernel/trace/trace.c: kernel/trace/trace.c:266:9: warning: no previous prototype for ‘buffer_ftrace_now’ [-Wmissing-prototypes] kernel/trace/trace.c:590:6: warning: no previous prototype for ‘free_snapshot’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.khe...@gmail.com> Reviewed-by: Josh Triplett <j...@joshtriplett.org> --- kernel/trace/trace.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/kernel/trace/trace.c b/kernel/trace/trace.c index 815c878..f097949 100644 --- a/kernel/trace/trace.c +++ b/kernel/trace/trace.c @@ -263,7 +263,7 @@ int call_filter_check_discard(struct ftrace_event_call *call, void *rec, } EXPORT_SYMBOL_GPL(call_filter_check_discard); -cycle_t buffer_ftrace_now(struct trace_buffer *buf, int cpu) +static cycle_t buffer_ftrace_now(struct trace_buffer *buf, int cpu) { u64 ts; @@ -587,7 +587,7 @@ static int alloc_snapshot(struct trace_array *tr) return 0; } -void free_snapshot(struct trace_array *tr) +static void free_snapshot(struct trace_array *tr) { /* * We don't free the ring buffer. instead, resize it because -- 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/
