[PATCH RFC 0/3] Remove NFS v2 support from the client and server

These patches will remove the all references and
support of NFS v2 in both the server and client.

On server side the support has been off, by default,
since 2013 (6b4e4965a6b). With this server patch the
ability to enable v2 will be remove.

Currently even with CONFIG_NFS_V2 not set
v2 mounts are still tied (over-the-wire). I looked at creating
a kernel parameter module so support could re-enabled
but that got ugly quick.

So I just decided to make all V2 mounts fail with
EOPNOTSUPP, with no way of turn them back on.

Steve Dickson (3):
nfsd: Remove the ability to enable NFS v2.
nfs.man: Remove references to NFS v2 from the man pages
mount: Remove NFS v2 support from mount.nfs
