From a9c1c3abe1160a5632e48c929b02b740556bf423 Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Mon, 1 Jun 2009 15:35:13 +0800 Subject: [PATCH] tracing/events: put TP_fast_assign into braces Currently TP_fast_assign has a limitation that we can't define local variables in it. Here's one use case when we introduce __dynamic_array(): TP_fast_assign( type *p = __get_dynamic_array(item); foo(p); bar(p); ), [ Impact: allow defining local variables in TP_fast_assign ] Signed-off-by: Li Zefan LKML-Reference: <4A2384B1.90100@cn.fujitsu.com> Signed-off-by: Steven Rostedt --- include/trace/ftrace.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/trace/ftrace.h b/include/trace/ftrace.h index 9276ec4f34de..ee9268222448 100644 --- a/include/trace/ftrace.h +++ b/include/trace/ftrace.h @@ -471,7 +471,7 @@ static void ftrace_raw_event_##call(proto) \ return; \ entry = ring_buffer_event_data(event); \ \ - assign; \ + { assign; } \ \ if (!filter_current_check_discard(event_call, entry, event)) \ trace_nowake_buffer_unlock_commit(event, irq_flags, pc); \ -- 2.20.1
