Too narrow because it's tied to scsi_device? Obviously it'd be easy
to expand the scsi_device_event enum to include LUNS_DATA_CHANGE or
something, and even the scsi_device_event_info struct can easily be
expanded if you need more info attached to the event. Let me know if
there's something specific I can help with.
