From dda61925f84d89e2f2a4597d6298a05a2bc05c20 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Fri, 28 Mar 2008 18:24:26 -0700 Subject: [UDP]: Move seq_ops from udp_iter_state to udp_seq_afinfo. No need to create seq_operations for each instance of 'netstat'. Signed-off-by: Denis V. Lunev Signed-off-by: David S.
