Next: perf: Fix perf probe build error
From: Frederic Weisbecker on 20 Apr 2010 20:10 When we run into dry run mode, we want to make write_kprobe_trace_event to succeed on writing the event. Let's initialize it to 0. Fixes the following build error: util/probe-event.c:1266: attention : «ret» may be used uninitialized in this function util/probe-event.c:1266: note: «ret» was declared here Signed-off-by: Frederic Weisbecker <fweisbec(a)gmail.com> Cc: Arnaldo Carvalho de Melo <acme(a)redhat.com> Cc: Masami Hiramatsu <mhiramat(a)redhat.com> Cc: Ingo Molnar <mingo(a)elte.hu> Cc: Peter Zijlstra <a.p.zijlstra(a)chello.nl> Cc: Paul Mackerras <paulus(a)samba.org> --- tools/perf/util/probe-event.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/tools/perf/util/probe-event.c b/tools/perf/util/probe-event.c index 3967f8f..4fb4803 100644 --- a/tools/perf/util/probe-event.c +++ b/tools/perf/util/probe-event.c @@ -1263,7 +1263,7 @@ static struct strlist *get_kprobe_trace_event_names(int fd, bool include_group) static int write_kprobe_trace_event(int fd, struct kprobe_trace_event *tev) { - int ret; + int ret = 0; char *buf = synthesize_kprobe_trace_command(tev); if (!buf) { -- 1.6.2.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
