Add a version of ksft_exit_fail_msg() which prints the errno and its
string form with ease. There is no benefit of exit message without
errno. Whenever some error occurs, instead of printing errno manually,
this function would be very helpful. In the next TAP ports or new tests,
this function will be used instead of ksft_exit_fail_msg() as it prints
errno.

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.
