Merge tag 'nfsd-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
 "This is a light release containing optimizations, code clean-ups, and
  minor bug fixes.

  This development cycle focused on work outside of upstream kernel
  development:

   - Continuing to build upstream CI for NFSD based on kdevops

   - Continuing to focus on the quality of NFSD in LTS kernels

   - Participation in IETF nfsv4 WG discussions about NFSv4 ACLs,
     directory delegation, and NFSv4.2 COPY offload

  Notable features for v6.11 that do not come through the NFSD tree
  include NFS server-side support for the new pNFS NVMe layout type
  [RFC9561]. Functional testing for pNFS block layouts like this one has
  been introduced to our kdevops CI harness. Work on improving the
  resolution of file attribute time stamps in local filesystems is also
  ongoing tree-wide.

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