Subject: NFS: Add version registering framework
This patch adds in the code to track multiple versions of the NFS
protocol. I created default structures for v2, v3 and v4 so that each
version can continue to work while I convert them into kernel modules.
I also removed the const parameter from the rpc_version array so that I
can change it at runtime.

Subject: NFS: Pass super operations and xattr handlers in the nfs_subversion
I can set all variables in the nfs_fill_super() function, allowing me to
remove the nfs4_fill_super() function.

The module (nfs2.ko) will be created in the same directory as nfs.ko and
will be automatically loaded the first time you try to mount over NFS v2.

From 1c606fb74c758beafd98cbad9a9133eadeec2371 Mon Sep 17 00:00:00 2001
From: Bryan Schumaker <bjschuma@netapp.com>
Date: Mon, 30 Jul 2012 16:05:24 -0400
Subject: NFS: Convert v3 into a module
This patch exports symbols and moves over the final structures needed by
the v3 module. In addition, I also switch over to using IS_ENABLED() to
check if CONFIG_NFS_V3 or CONFIG_NFS_V3_MODULE are set.
The module (nfs3.ko) will be created in the same directory as nfs.ko and
will be automatically loaded the first time you try to mount over NFS v3.
