Pull nfsd updates from Chuck Lever:
"This release completes the SunRPC thread scheduler work that was begun
in v6.6. The scheduler can now find an svc thread to wake in constant
time and without a list walk. Thanks again to Neil Brown for this
overhaul.

Lorenzo Bianconi contributed infrastructure for a netlink-based NFSD
control plane. The long-term plan is to provide the same functionality
as found in /proc/fs/nfsd, plus some interesting additions, and then
migrate the NFSD user space utilities to netlink.

A long series to overhaul NFSD's NFSv4 operation encoding was applied
in this release. The goals are to bring this family of encoding
functions in line with the matching NFSv4 decoding functions and with
the NFSv2 and NFSv3 XDR functions, preparing the way for better memory
safety and maintainability.

A further improvement to NFSD's write delegation support was
contributed by Dai Ngo. This adds a CB_GETATTR callback, enabling the
server to retrieve cached size and mtime data from clients holding
write delegations. If the server can retrieve this information, it
does not have to recall the delegation in some cases.

The usual panoply of bug fixes and minor improvements round out this
release. As always I am grateful to all contributors, reviewers, and
testers"
