Merge tag 'nfsd-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull nfsd updates from Chuck Lever:
"The bulk of the patches for this release are optimizations, code
clean-ups, and minor bug fixes.
One new feature to mention is that NFSD administrators now have the
ability to revoke NFSv4 open and lock state. NFSD's NFSv3 support has
had this capability for some time.
As always I am grateful to NFSD contributors, reviewers, and testers"
