charset="utf-8" Content-Transfer-Encoding: quoted-printable From: Matias Bj=C3=B8rling The NVMe 2.0 specification adds an independent identify namespace data structure that contains generic attributes that apply to all namespace types. Some attributes carry over from the NVM command set identify namespace data structure, and others are new. Currently, the data structure only considered when CRIMS is enabled or when the namespace type is key-value. However, the independent namespace data structure is mandatory for devices that implement features from the 2.0+ specification. Therefore, we can check this data structure first. If unavailable, retrieve the generic attributes from the NVM command set identify namespace data structure. Signed-off-by: Matias Bj=C3=B8rling Reviewed-by: Martin K.
