The version 4 nfsd delegation implementation uses leases to co-ordinate behavior between local, samba, and nfs access. The main design points are - Seperate the file_lock processing from the file descriptor processing in fcntl_setlease. - New non-file descriptor interface to setlease - Use new lock manager callbacks to allow nfsd to create, break, and release leases. - Provide default lock manager callbacks for fcntl_setlease -->Andy Adamson
