Date: Fri, 6 Dec 2013 14:23:38 +0800 From: Wang Weidong <wangweidong1@...wei.com> To: <jon.maloy@...csson.com>, <allan.stephens@...driver.com>, <davem@...emloft.net> CC: <netdev@...r.kernel.org>, <tipc-discussion@...ts.sourceforge.net> Subject: [PATCH net-next 2/6] tipc: remove the unnecessary variable the sseq variable is unnecessary in tipc_subseq_alloc, so remove it. sk in tipc_sock_create_local is never used, so remove it. res in __tipc_disconnect is unnecessary, so remove it. limit in rcvbuf_limit is unnecessary, so remove it.
