From 29f93943d1916d1a3faa3f10f4a06994347ac990 Mon Sep 17 00:00:00 2001 From: Steven Rostedt <srostedt@redhat.com> Date: Fri, 8 May 2009 16:06:47 -0400 Subject: tracing: initialize return value for __ftrace_set_clr_event Commit 8f31bfe538ebafac187d2d4465a92e1d9ee6d8c2 tracing/events: clean up for ftrace_set_clr_event() Moved out the code for ftrace_set_clr_event into a helper funciton but did not initialize the return value. As a result, we do not warn about a typo in the echoing of events in set_event. This patch restores the old warning: # echo foobar > set_event -bash: echo: write error: Invalid argument [ Impact: restore warning of invalid entries to set_event ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org> --- kernel/trace/trace_events.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/trace/trace_events.c b/kernel/trace/trace_events.c index df394bc6d54..2eecb87e42d 100644 --- a/kernel/trace/trace_events.c +++ b/kernel/trace/trace_events.c @@ -118,7 +118,7 @@ static int __ftrace_set_clr_event(const char *match, const char *sub, const char *event, int set) { struct ftrace_event_call *call; - int ret; + int ret = -EINVAL; mutex_lock(&event_mutex); list_for_each_entry(call, &ftrace_events, list) { -- cgit v1.2.3
