  Log:
  Expand the diskslice->ds_openmask from 8 bits to 256 bits to cover all
  possible partitions.  Partitions from 'i' on, and the whole-disk partition,
  were not being properly tracked, resulting in multiple device opens and
  device closes to the underlying device.
  
  In particular, this caused USB memory sticks to connect to the CAM driver
  with ever-increasing DA#n unit numbers because CAMs reference counting got
  seriously corrupted.
