    sys/kern             kern_conf.c kern_device.c 
  Log:
  Because destroy_all_dev() checks the mask/match against the device's si_udev,
  which is a field combining both major and minor numbers, we must mask off the
  major bits (to retain only the minor bits) from the 'mask' variable in order
  to allow a generic -1 to be passed as the mask.  Otherwise we will not match
  anything.
  
  Revamp a good chunk of the documentation to try to make the major/minor
  number masking issues clear.
