[PATCH v2 00/14] NFS: Make NFS v4.0 KConfig-urable

[Anna Schumaker <anna@kernel.org>]

From: Anna Schumaker <anna.schumaker@oracle.com>

A desire to deprecate NFS v4.0 came up as a discussion topic during the
October Bake-a-thon last year. This patchset takes the first step by
moving NFS v4.0 only code into new files prefixed with "nfs40" and
introducing a KConfig option to compile without NFS v4.0 support.

At the same time, I promote NFS v4.1 to be the default NFSv4
minorversion included in the kernel to prevent the situation where we
have NFS v4 enabled without any minor versions.

Changes in v2:
- KConfig-out NFS v4.0-only operations from nfs4xdr.c
- Fix a kernel test robot build warning

Thoughts?
Anna
