Subject: [PATCH 4/8] tracing: Conver more sched events to DEFINE_EVENT
Date: Mon, 24 May 2010 16:23:35 +0800	[thread overview]
Message-ID: <4BFA3787.2040800@cn.fujitsu.com> (raw)
In-Reply-To: <4BFA3728.3000701@cn.fujitsu.com>

Convert sched_wait_task to DEFINE_EVENT, and save ~1K:

   text    data     bss     dec     hex filename
 104595    9424    4992  119011   1d0e3 kernel/sched.o.orig
 103619    9344    4992  117955   1ccc3 kernel/sched.o

No change in functionality.
