From c860c6b1479992440e4962e9c95d258bfdce4fca Mon Sep 17 00:00:00 2001 From: Julius Volz Date: Tue, 2 Sep 2008 15:55:36 +0200 Subject: IPVS: Add internal versions of sockopt interface structs Add extended internal versions of struct ip_vs_service_user and struct ip_vs_dest_user (the originals can't be modified as they are part of the old sockopt interface). Adjust ip_vs_ctl.c to work with the new data structures and add some minor AF-awareness.
