Since commit f931d8374c ("nfs/blocklayout: refactor block device
opening"), an error is reported when no multi-path device is found.
But this isn't a fatal error if the subsequent device open is
successful. On systems without multi-path devices, this message
always appears whether there is a problem or not.
Instead, generate less system journal noise by reporting an error
only when both open attempts fail. The new error message is more
actionable since it indicates that there is a real configuration
issue to be addressed.

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.
