    sys/kern             device_if.m subr_bus.c 
  Log:
  Implement device_quiesce.  This method means 'you are about to be
  unloaded, cleanup, or return ebusy of that's inconvenient.'  The
  default module hanlder for newbus will now call this when we get a
  MOD_QUIESCE event, but in the future may call this at other times.
  
  This shouldn't change any actual behavior until drivers start to use it.
