    nfs_nfsdsocket.c: All Copy and Clone across file systems
    
    For some server file system types, such as ZFS, a Copy/Clone
    operation can be done across file systems of the same file
    system type.
    
    As such, this patch allows the Copy/Clone to be attempted
    when the file handles are for files on different file systems.
    
    This fixes a problem for exported ZFS file systems when a
    copy_files on file_range(2) between file systems in the same
    NFSv4 mount is attempted.
