This patch series refactors all futex selftests to use kselftest_harness.h instead of futex's logging.h, as discussed here [1].
This allows to remove a lot of boilerplate code and to simplify some parts of the test logic, mainly when the test needs to exit early. The result of this is more than 500 lines removed from tools/testing/selftests/futex/. Also, this enables new tests to use kselftest.h features like ASSERT_s and such.
There are some caveats around this refactor: - logging.h had verbosity levels, while kselftest_harness.h doesn't. I created a new print function called ksft_print_dbg_msg() that prints the message if the user uses the -d flag, so now there's an equivalent of this feature. - futex_requeue_pi test accepted command line arguments to be used as test parameters (e.g. ./futex_requeue_pi -b -l -t 500000). This doesn't work with kselftest_harness.h because there's no straightforward way to send command line arguments to the test. I used FIXTURE_VARIANT() to achieve the same result, but now the parameters live inside of the test file, instead of on functional/run.sh. This increased a little bit the number of test cases for futex_requeue_pi, from 22 to 24.
Although there are a lot of patches, they follow a simple pattern: - The usage() function, options parsing, kseftest setup (ksft_print_header(), ksft_set_plan(), ksft_print_cnts()), are all gone - info() is replaced with ksft_print_dbg_msg() - Exit on error paths are replaced with ksft_exit_fail_msg() - fail/pass replaced with their ksft_ equivalents.
I have compared the results of run.sh before and after this patchset and didn't find any regression from the test results.
Thanks, André

Best regards,
Create ksft_print_dbg_msg() so testers can enable extra debug messages when running a test with the flag -d.

To reduce the boilerplate code, refactor futex_requeue_pi test to use kselftest_harness header instead of futex's logging header.
Use kselftest fixture feature to make it easy to repeat the same test with different parameters. With that, drop all repetitive test calls from run.sh.
