OK, then this will work on all architectures I know:

struct nvme_passthru_cmd64 {
        __u8	opcode;
	__u8	flags;
	__u16	rsvd1;
	__u32	nsid;
	__u32	cdw2;
	__u32	cdw3;
	__u64	metadata;
	__u64	addr;
	__u32	metadata_len;
	__u32	data_len;
	__u32	cdw10;
	__u32	cdw11;
	__u32	cdw12;
	__u32	cdw13;
	__u32	cdw14;
	__u32	cdw15;
	__u32	timeout_ms;
        __u32   rsvd2;
	__u64	result;
};
