The pstore dump function doesn't alert at all on errors - despite pstore is usually a last resource and if it fails users won't be able to read the kernel log, this is not the case for server users with serial access, for example. So, let's at least attempt to inform such advanced users on the first backend writing error detected during the kmsg dump - this is also very useful for pstore debugging purposes.

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.
