Date: Tue, 8 Apr 2008 17:34:26 +0400 From: "Denis V. Lunev" <den@...nvz.org> To: davem@...emloft.net Cc: netdev@...r.kernel.org, "Denis V. Lunev" <den@...nvz.org> Subject: [PATCH 3/6 net-2.6.26] [TCP]: Move seq_ops from tcp_iter_state to tcp_seq_afinfo. No need to create seq_operations for each instance of 'netstat'.
