Merge tag 'nfsd-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
 "Notable features of this release include:

   - Pre-requisites for automatically determining the RPC server thread
     count

   - Clean-up and preparation for supporting LOCALIO, which will be
     merged via the NFS client tree

   - Enhancements and fixes to NFSv4.2 COPY offload

   - A new Python-based tool for generating kernel SunRPC XDR encoding
     and decoding functions, added as an aid for prototyping features in
     protocols based on the Linux kernel's SunRPC implementation

  As always I am grateful to the NFSD contributors, reviewers, testers,
  and bug reporters who participated during this cycle"
