  Log:
  With the introduction of UFS2 we started looking for superblocks in
  four different locations on a prospective filesystem.
  
  If we found none, we forgot to invalidate the four buffers, thus the
  following sequence would fails:
  
          (md0 = blank disk)
          mount /dev/md0 /mnt
          (fails, no superblocks)
          newfs /dev/md0
          (writes using physio which does not go through buffercache).
          mount /dev/md0 /mnt
          (still fails, the four cached buffers still contain no superblocks)
