From 07feaebfcc10cd35e745c7073667935246494bee Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 12 Sep 2007 11:58:02 +0200 Subject: [NET]: Add a network namespace parameter to struct sock Sockets need to get a reference to their network namespace, or possibly a simple hold if someone registers on the network namespace notifier and will free the sockets when the namespace is going to be destroyed.
