Oh, sorry about that. The function is added in the following patch, "[PATCH v3 09/18] kunit: test: add support for test abort"[1]. My apologies if this patch is supposed to come after it in sequence, but I assumed it should come before otherwise objtool would complain about the symbol when it is introduced. Thanks!

Or send me all patches such that I have context, or have a sane Changelog that gives me context. Just don't give me one patch with a crappy changelog.
