/* GNU Hurd NOTE: The size of this structure (16 ints) is known in
   <hurd/hurd_types.defs>, since it is used in the `file_statfs' RPC.  MiG
   does not cope at all well with the passed C structure not being of the
   expected size.  There are some filler words at the end to allow for
   future expansion.  To increase the size of the structure used in the RPC
   and retain binary compatibility, we would need to assign a new message
   number.  */
