I think SCSI already has it or am I imagining things again? :-)

IMHO, if it's genhd.capability_flags then the flag should be MEDIA_CHANGE_NOTIFY not ASYNC_NOTIFICATION because AN itself doesn't imply any specific event. It's just a notification mechanism, for ATAPI devices, it means media change, for PMP it has a different meaning, so I think we need to export the processed meaning not the specific mechanism to userland.
Thanks.
