Hello Linus-
Aside from observing the significant substance of this PR, one
housekeeping item of note is the first commit in the series,
which is a second fix for c96e2a695e00 ("sunrpc: set the
bv_offset of first bvec in svc_tcp_sendmsg").
The bug was reported during -rc7 and the test results became
available only after the v6.6 merge window opened. Thus I have
rebased the nfsd v6.6 PR on that fix so it can be backported
swiftly and easily to v6.5.y. The reporter has confirmed that
both this small fix and the more significant related changes
in v6.6 do not trigger his qcow2 direct I/O reproducer.
Many and great thanks to all contributors and testers for this
release of nfsd.

NFSD 6.6 Release Notes
I'm thrilled to announce that the Linux in-kernel NFS server now
offers NFSv4 write delegations. A write delegation enables a client
to cache data and metadata for a single file more aggressively,
reducing network round trips and server workload. Many thanks to Dai
Ngo for contributing this facility, and to Jeff Layton and Neil
Brown for reviewing and testing it.
This release also sees the removal of all support for DES- and
triple-DES-based Kerberos encryption types in the kernel's SunRPC
implementation. These encryption types have been deprecated by the
Internet community for years and are considered insecure. This
change affects both the in-kernel NFS client and server.
The server's UDP and TCP socket transports have now fully adopted
David Howells' new bio_vec iterator so that no more than one
sendmsg() call is needed to transmit each RPC message. In
particular, this helps kTLS optimize record boundaries when sending
RPC-with-TLS replies, and it takes the server a baby step closer to
handling file I/O via folios.
We've begun work on overhauling the SunRPC thread scheduler to
remove a costly linked-list walk when looking for an idle RPC
service thread to wake. The pre-requisites are included in this
release. Thanks to Neil Brown for his ongoing work on this
improvement.
