> The DIOCSBAD ioctl sets a bad block table (is almost suredly called by
> the bad144 utility) and changes the memory-resident bad block table.  The
> problem is that bad144intern() is not called after the "disk" structure has
> been changed, so that the internal bad144 table will become out-of-sync with
> the one in the disk structure.
