If a PR operation fails we can return a device-specific error which is impossible to handle in some cases because we could have a mix of devices when DM is used, or future users like LIO only knows it's interacting with a block device so it doesn't know the type. This patch adds a new pr_status enum so drivers can convert errors to a common type which can be handled by the caller.

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.
