[Qemu-devel] [PATCH] SCSI update to the correct sense code for media rem

List, Paolo

Please find a trivial patch that changes the sense code for errors when trying, 
and failing, to eject media using the START_STOP_UNIT command when the medium 
is locked down by a previous PREVENT_ALLOW_MEDIUM_REMOVAL command.

MMC Annex F lists MEDIUM_REMOVAL_PREVENTED as the recommended sense code for 
this error.

This now passes the test that a SCSI target retports the corre3ct sense code(s) 
for medium removal protection :

iscsi-test --dataloss --test="*prevent*eject*" 
Try to set PREVENTALLOW ... [OK]
Try to eject the media ... Eject failed. [OK]
Load the media again in case it was ejected ... [OK]
Clear the PREVENTALLOW again ... [OK]
TEST T0381_preventallow_eject [OK]
