Let me add more information about this,

Kees Cook, has done the work of a kselftest results parser in perl
which is in the test-definitions repository. which was working well
for two years now. please refer to the below commit log and link to
the kselftest test-definitions [3].

The new test cases output is not coping up with the old results parser
and both KernelCI [1] and LKFT [2] using LAVA have noticed.
Kselftest results parser problem [4].

kselftest: Parse kTAP for test results

This stops mangling test output for humans and performs a best-effort
kTAP parsing for the kselftest output (including recursive kTAP output).
