Hi Lorenzo and Muhammad
Reviving this thread since the merging window is closed and we have
more time to review /work on this code in the next few weeks.

Specifically regarding Lorenzo's comments about FAIL_TEST_IF_FALSE
Muhammad Usama Anjum doesn't want assert being used in selftest (see
[1] above), and I quote:
"We don't want to terminate the test if one test fails because of assert. We
want the sub-tests to get executed in-dependent of other tests.
ksft_test_result(condition, fmt, ...);
ksft_test_result_pass(fmt, ...);"
FAIL_TEST_IF_FALSE is a wrapper for ksft_test_result macro, and
replacement of assert.
Please let me know if you have questions on this and Muhammad might
also help to clarify the requirement if needed.
Thanks
