Some ublk selftests have strange behavior when fio is not installed. While most tests behave correctly (run if they don't need fio, or skip if they need fio), the following tests have different behavior: - test_null_01, test_null_02, test_generic_01, test_generic_02, and test_generic_12 try to run fio without checking if it exists first, and fail on any failure of the fio command (including "fio command not found"). So these tests fail when they should skip. - test_stress_05 runs fio without checking if it exists first, but doesn't fail on fio command failure. This test passes, but that pass is misleading as the test doesn't do anything useful without fio installed. So this test passes when it should skip. Fix these issues by adding _have_program fio checks to the top of all of these tests.

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.
