Usage

void nvme_init_io (struct libnvme_passthru_cmd *cmd , __u8 opcode , __u32 nsid , __u64 slba , void *data , __u32 data_len , void *metadata , __u32 metadata_len );

Arguments

`cmd`	Passthru command to use
`opcode`	Opcode to execute
`nsid`	Namespace ID
`slba`	Starting logical block
`data`	Pointer to user address of the data buffer
`data_len`	Length of user buffer, data, in bytes
`metadata`	Pointer to user address of the metadata buffer
`metadata_len`	Length of user buffer, metadata, in bytes
