+Subject: [PATCH 3/6] scsi-disk: define props in scsi_block_disk to avoid
+ memleaks
+
+scsi_block_realize() use scsi_realize() to init some props, but
+these props is not defined in scsi_block_disk_properties, so they will
+not be freed.
+
+This patch defines these prop in scsi_block_disk_properties to avoid memleaks.
