a good way of quickly testing everything applicable to the current
config.
KUnit can be enabled or disabled at boot time, and this behavior is
controlled by the kunit.enable kernel parameter.
By default, kunit.enable is set to 1 because KUNIT_DEFAULT_ENABLED is
enabled by default. To ensure that tests are executed as expected,
verify that kunit.enable=1 at boot time.
Once we have built our kernel (and/or modules), it is simple to run
the tests. If the tests are built-in, they will run automatically on the
kernel boot. The results will be written to the kernel log (``dmesg``)
