Biederman" Date: Mon, 6 Aug 2012 08:42:04 +0000 Subject: sctp: Make the address lists per network namespace - Move the address lists into struct net - Add per network namespace initialization and cleanup - Pass around struct net so it is everywhere I need it. - Rename all of the global variable references into references to the variables moved into struct net Signed-off-by: "Eric W.
