NFSD 6.12 Release Notes

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.
