Update to the patches that allow the "nfs" file system to handle
vers=4. These patches are for discussion only.
Minor changes to mount.nfs and umount.nfs are required, and will be
posted in a separate thread. With these changes, mount.nfs passes a
client_address option and skips rpcbind for vers=4 mounts, and
umount.nfs skips the UMNT call for vers=4 mounts.
This series adds proper handling of the default port (0 for v2/v3,
2049 for v4), teaches nfs_kill_super to handle both "nfs" and "nfs4"
file systems, and refactors NFSv4 routines so common code can be
invoked by "nfs" and "nfs4."
Simple mount test succeeds. /proc/mounts lists the mount as "nfs4"
but /etc/mtab lists it as "nfs". Thus combining nfs_kill_super and
nfs4_kill_super is probably not necessary.
I have not tried cross mounts or referrals.
