Subject: [PATCH v2 1/2] NFSD: Remove CONFIG_NFSD_V3
Eventually support for NFSv2 in the Linux NFS server is to be
deprecated and then removed.
However, NFSv2 is the "always supported" version that is available
as soon as CONFIG_NFSD is set. Before NFSv2 support can be removed,
we need to choose a different "always supported" version.
This patch removes CONFIG_NFSD_V3 so that NFSv3 is always supported,
as NFSv2 is today. When NFSv2 support is removed, NFSv3 will become
the only "always supported" NFS version.
The defconfigs still need to be updated to remove CONFIG_NFSD_V3=y.
