History

bouyer f6f9f8a965 Change DIOCEJECT to do what's needed to eject a device before the eject command (unlock for sd and cd) if no other partitions are open, return EBUSY otherwise. DIOCEJECT will have the old semantic if its argument is not 0. The old ioctl has been renamed to ODIOCEJECT for binary compatibility.		1999-02-08 16:33:16 +00:00
