      26     <hurd/hurd_types.defs>, since it is used in the `file_statfs' RPC.  MiG
      27     does not cope at all well with the passed C structure not being of the
      28     expected size.  There are some filler words at the end to allow for
      29     future expansion.  To increase the size of the structure used in the RPC
      30     and retain binary compatibility, we would need to assign a new message
      31     number.
      32  
      33     Note also that `struct statvfs' in <bits/statvfs.h> is laid out
      34     identically to `struct statfs', so they can be used interchangeably.
      35     Any changes made here must also be made in that file.  */
