xenbus_va_dev_error() will try to write error messages to Xenstore under the error/<dev-name>/error node (with <dev-name> something like "device/vbd/51872"). This will fail normally and another message about this failure is added to dmesg. I believe this is a remnant from very ancient times, as it was added in the first pvops rush of commits in 2007. So remove the additional message when writing to Xenstore failed as a minimum step.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
