Christoph Hellwig fab72f5a04 nvme: call nvme_identify_ns as the first thing in nvme_alloc_ns_block
Check if the namespace actually exists as the very first thing and don't
bother with any extra work if not.  This should speed up and simplify
the sequential scanning for NVMe 1.0 devices.

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 Restructured Text 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.
