I found unwanted side effect, open() with O_NONBLOCK also successes when there is no medium. Unfortunately, we ignore I/O errors for CDROMs to support some crazy hybrid media -- so overall result is many I/O warnings in system logs. I have added CDROM_DRIVE_STATUS to the logic to stop probing when there is no medium.
