Subject: [PATCH net-next-2.6 8/9] sctp: make heartbeat information in sctp_make_heartbeat()
Date: Wed, 20 Apr 2011 15:31:47 +0800	[thread overview]
Message-ID: <4DAE8BE3.2050607@cn.fujitsu.com> (raw)
In-Reply-To: <4DAE8A27.3040007@cn.fujitsu.com>

Make heartbeat information in sctp_make_heartbeat() instead
of make it in sctp_sf_heartbeat() directly for common using.
