Subject: [PATCH 1/3] kunit: tool: remove dead parse_crash_in_log() logic
This logic depends on the kernel logging a message containing
'kunit test case crashed', but there is no corresponding logic to do so.
This is likely a relic of the revision process KUnit initially went
through when being upstreamed.
Delete it given
1) it's been missing for years and likely won't get implemented
2) the parser has been moving to be a more general KTAP parser,
kunit-only magic like this isn't how we'd want to implement it.
