[PATCH nfs-utils v2 0/4] nfsdctl: new nfs-utils tool for managing the kernel NFS server

[Jeff Layton <jlayton@kernel.org>]

Lorenzo posted an updated version of his netlink interface patches
yesterday [1]. This is an update to adapt to those changes, and to bring
the tool closer to feature completion for release.

This series first adds Lorenzo's original userland nfsdctl tool to the
nfs-utils tree, and then converts it to a subcommand-based interface, in
the spirit of tools like nmcli or virsh.

This version should be at feature parity with rpc.nfsd. This posting
also includes a manpage and an update to the nfs-server.service to
start using the new interface when possible.

I've also included a patch that adds the manpage source. It's much nicer
to edit that and regenerate it if we have to update it later. We can
drop that patch if you just want to keep the result though.

Assuming we're good with the new kernel interfaces, this should be
pretty close to ready for merge.
