 After finishing my assessment of struct ifid.ifid_start,
 i now understand better the remark of Taylor R Campbell in
 "The ifid_start field seems to be unused, incidentally,
  so we needn't even expand the size of cd9660 file handles."
 I had the wrong impression that struct fid would be a maximum
 sized wrapper, like a union. But now i see the size inquiry
 protocol of VFS_VPTOFH(,fh_size).
 So i will update my patch by a few ifdefs which exclude the
 member .ifid_start from struct ifid by default.
 For completeness, i also quote Taylor's other remark:
 "As an aside, it seems from glancing at struct ufid in ufs/ufs/inode.h
  that UFS will have a similar 32-bit overflow problem."
