From f15364bd4cf8799a7677b6daeed7b67d9139d974 Mon Sep 17 00:00:00 2001 From: Aurélien Charbon Date: Fri, 18 Jan 2008 15:50:56 +0100 Subject: IPv6 support for NFS server export caches MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds IPv6 support to the interfaces that are used to express nfsd exports. All addressed are stored internally as IPv6; backwards compatibility is maintained using mapped addresses.
