Set BLK_FEAT_ATOMIC_WRITES_STACKED to enable atomic writes. All other stacked device request queue limits should automatically be set properly. With regards to atomic write max bytes limit, this will be set at hw_max_sectors and this is limited by the stripe width, which we want.

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.
