| |
The struct scsi_varlen_cdb_hdr is expected to be exactly 10 bytes when used in struct osd_cdb_head, but it isn't marked as packed. Some architectures will round the struct size up which triggers BUILD_BUG_ON compile errors in osd_initiator.c when the outer structs are unexpected sizes. This is fixed by marking struct scsi_varlen_cdb_hdr as __packed.
