Hello Linus-

Stephen Rothwell notes one or two minor merge conflicts with the VFS
tree, which I believe you've already merged. He's been carrying
fix-ups in linux-next for several weeks with no reported issues.

  NFSD: Clean up nfsd4_encode_replay() (2024-03-09 13:57:50 -0500)

----------------------------------------------------------------
NFSD 6.9 Release Notes

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.
