Subject: [PATCH 44/79] IPVS: netns, common protocol changes and use of appcnt.
Date: Wed, 19 Jan 2011 20:14:44 +0100	[thread overview]
Message-ID: <1295464519-21763-45-git-send-email-kaber@trash.net> (raw)
In-Reply-To: <1295464519-21763-1-git-send-email-kaber@trash.net>

From: Hans Schillstrom <hans.schillstrom@ericsson.com>

appcnt and timeout_table moved from struct ip_vs_protocol to
ip_vs proto_data.

struct net *net added as first param to
 - register_app()
 - unregister_app()
 - app_conn_bind()
 - ip_vs_conn_new()

[horms@verge.net.au: removed cosmetic-change-only hunk]
