Subject [PATCH] SCSI not showing tray status correctly
Date Mon, 27 Dec 2004 06:26:32 +0100
Digg This When trying to get the drive status via ioctl CDROM_DRIVE_STATUS, with no disk
it gives CDS_TRAY_OPEN even if the tray is closed.
ioctl works as expected with ide-cd driver. Here is the patch to get the same
behaviour on SCSI drives for kernel 2.6.10. 2.4 branch have same problem.
