From: Frederic Weisbecker Date: Sat, 30 May 2009 02:25:30 +0000 (+0200) Subject: tracing/stat: remove unappropriate safe walk on list X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=43bd1236234cacbc18d1476a9b57e7a306efddf5;p=openwrt%2Fstaging%2Fblogic.git tracing/stat: remove unappropriate safe walk on list register_stat_tracer() uses list_for_each_entry_safe to check whether a tracer is already present in the list. But we don't delete anything from the list here, so we don't need the safe version [ Impact: cleanup list use is stat tracing ] Signed-off-by: Frederic Weisbecker --- diff --git a/kernel/trace/trace_stat.c b/kernel/trace/trace_stat.c index 17f20ebdad2a..c00643733f4c 100644 --- a/kernel/trace/trace_stat.c +++ b/kernel/trace/trace_stat.c @@ -316,7 +316,7 @@ static int init_stat_file(struct stat_session *session) int register_stat_tracer(struct tracer_stat *trace) { - struct stat_session *session, *node, *tmp; + struct stat_session *session, *node; int ret; if (!trace) @@ -327,7 +327,7 @@ int register_stat_tracer(struct tracer_stat *trace) /* Already registered? */ mutex_lock(&all_stat_sessions_mutex); - list_for_each_entry_safe(node, tmp, &all_stat_sessions, session_list) { + list_for_each_entry(node, &all_stat_sessions, session_list) { if (node->ts == trace) { mutex_unlock(&all_stat_sessions_mutex); return -EINVAL;
