Subject: [PATCH 7/9] sunrpc: Tag rpc_xprt with net
Date: Wed, 29 Sep 2010 16:05:43 +0400	[thread overview]
Message-ID: <4CA32B97.9000802@parallels.com> (raw)
In-Reply-To: <4CA32AB4.2090808@parallels.com>

The net is known from the xprt_create and this tagging will also
give un the context in the conntection workers where real sockets
are created.
