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)
