If the Namespace Identifier (NSID) field specifies an active NSID, then the
Identify Namespace data structure is returned to the host for that specified
namespace.
If the controller supports the Namespace Management capability and the NSID
field is set to NVME_NSID_ALL, then the controller returns an Identify
Namespace data structure that specifies capabilities that are common across
namespaces for this controller.
See
struct nvme_id_ns for details on the structure returned.
The nvme command status if a response was received (see
enum
nvme_status_field) or -1 with errno set otherwise.
