Subject: [PATCH 2/2] ftrace: Output REC->var instead of __entry->var for trace format
Date: Wed, 08 Apr 2009 17:00:13 +0800	[thread overview]
Message-ID: <49DC679D.2090901@cn.fujitsu.com> (raw)
In-Reply-To: <49DC6751.30308@cn.fujitsu.com>

print fmt: "irq=%d return=%s", __entry->irq, __entry->ret ? \"handled\" : \"unhandled\"

"__entry" should be convert to "REC" by __stringify() macro.
