Subject: [PATCH] scsi: cdrom: Fix crash after remote cdrom detached
|
|
|
|
There is a small window between the twice blk_is_available in
|
|
scsi_disk_emulate_command which would cause crash due to the later
|
|
assertion if the remote cdrom is detached in this window.
|
|
|
|
So this patch replaces assertions with return to avoid qemu crash.
