DESCRIPTION
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.

RETURN
