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 Bjørling <matias.bjorling@wdc.com> Reviewed-by: Martin K.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
