From: Li Zefan 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 files changed, 1 insertions(+), 1 deletions(-) diff --git a/include/trace/ftrace.h b/include/trace/ftrace.h index 9276ec4..ee92682 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); \ -- 1.6.3.1 -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
