Alexander,

would it make sense for scsi_cd to also use GET EVENT STATUS NOTIFICATION
command (4A) with Polled flag and Media bit set in Notification Class in
addition to TUR for devices that do not support asynchronous notification?

I think that this should increase reliability of detecting CD media changes
between polls.
