Message-ID: <4A488667.6040004@cn.fujitsu.com> Date: Mon, 29 Jun 2009 17:16:23 +0800 From: Xiao Guangrong <xiaoguangrong@...fujitsu.com> To: Ingo <mingo@...e.hu> CC: Frederic Weisbecker <fweisbec@...il.com>, Steven Rostedt <rostedt@...dmis.org>, LKML <linux-kernel@...r.kernel.org> Subject: [PATCH] tracing/syscall: remove redundant code No need to call trace_wake_up() explicitly because it's called in trace_current_buffer_unlock_commit().
