The physical_volume, volume_group, logical_volume and lv_segment structures' 'status' member is now uint64_t. The alignment of these structures was also audited to remove holes. The movement of some members in 'volume_group' and 'lv_segment' eliminates holes. The 'physical_volume' structure still has one 4-byte hole after 'pe_size'; the other structures no longer have any holes. Each structures' size has not changed.
