----------------------------------------------------------------
NFS client updates for Linux 6.19

Highlights include:

Bugfixes:
- Fix 'nlink' attribute update races when unlinking a file.
- Add missing initialisers for the directory verifier in various places.
- Don't regress the NFSv4 open state due to misordered racing replies.
- Ensure the NFSv4.x callback server uses the correct transport
  connection.
- Fix potential use-after-free races when shutting down the NFSv4.x
  callback server.
- Fix a pNFS layout commit crash.
- Assorted fixes to ensure correct propagation of mount options when the
  client crosses a filesystem boundary and triggers the VFS automount
  code.
- More localio fixes.

Features and cleanups:
- Add initial support for basic directory delegations.
- SunRPC back channel code cleanups.
