Hi Kujau,
It seems like a different issue, something wrong with
void nfs_fs_proc_net_exit(struct net *net)
{
struct nfs_net *nn = net_generic(net, nfs_net_id);
remove_proc_entry("volumes", nn->proc_nfsfs);
remove_proc_entry("servers", nn->proc_nfsfs);
remove_proc_entry("fs/nfsfs", NULL);
}
But I'm not familiar with this piece of code.
Regards!
Gerry
