AN is a generic concept that I feel will propagate elsewhere.
I think SCSI already has it or am I imagining things again? :-)
Though perhaps it should be in a 'capability_flags' file rather than a
'media_change_event' file.
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.
