    Merge tag 'nfsd-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

    Pull nfsd updates from Chuck Lever:
     "Neil Brown contributed more scalability improvements to NFSD's open
      file cache, and Jeff Layton contributed a menagerie of repairs to
      NFSD's NFSv4 callback / backchannel implementation.

      Mike Snitzer contributed a change to NFS re-export support that
      disables support for file locking on a re-exported NFSv4 mount. This
      is because NFSv4 state recovery is currently difficult if not
      impossible for re-exported NFS mounts. The change aims to prevent data
      integrity exposures after the re-export server crashes.

      Work continues on the evolving NFSD netlink administrative API.

      Many thanks to the contributors, reviewers, testers, and bug reporters
      who participated during the v6.15 development cycle"
