 "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"
