Allow ZNS NVMe SSDs to present a read-only namespace when append is not supported, instead of rejecting the namespace directly. This allows (i) the namespace to be used in read-only mode, which is not a problem as the append command only affects the write path, and (ii) to use standard management tools such as nvme-cli to choose a different format or firmware slot that is compatible with the Linux zoned block device.

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.
