From 7ea34ac15e45b790f2faa7d5f69c560a43f2de70 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 21 Mar 2012 09:52:05 -0400 Subject: nfsd: add a per-net-namespace struct for nfsd Eventually, we'll need this when nfsd gets containerized fully. For now, create a struct on a per-net-namespace basis that will just hold a pointer to the cld_net structure. That struct will hold all of the per-net data that we need for the cld tracker. Eventually we can add other pernet objects to struct nfsd_net. Signed-off-by: Jeff Layton Signed-off-by: J.
