  26 /* GNU Hurd NOTE: The size of this structure (16 ints) is known in
  27    <hurd/hurd_types.defs>, since it is used in the `file_statfs' RPC.  MiG
  28    does not cope at all well with the passed C structure not being of the
  29    expected size.  There are some filler words at the end to allow for
  30    future expansion.  To increase the size of the structure used in the RPC
  31    and retain binary compatibility, we would need to assign a new message
  32    number.
  33
  34    Note also that `struct statvfs' in <bits/statvfs.h> is laid out
  35    identically to `struct statfs', so they can be used interchangeably.
  36    Any changes made here must also be made in that file.  */
