This is fixed by marking struct scsi_varlen_cdb_hdr as __packed. What actual problem have you encountered? The structure is {u8[8], u16} which is naturally packed on every architecture I know about. I've even built osd_initiator without problem on parisc, which has some of the most rigid alignment rules I've seen.
