Hmm, it looks like executor_test.c might not have made it into kunit-fixes.
I believe this is the applied version of this patch:

$ git show d833ce7480864d4d7eb2dbb04320858be3578b2a --stat

    kunit: Fix merge issue in suite filtering test
...
 lib/kunit/executor.c | 2 +-
 1 file changed, 1 insertion(+), 1 deletion(-)

The result looks like this:
$ ./tools/testing/kunit/kunit.py run
...
$ make ARCH=um --jobs=8 O=.kunit
ERROR:root:../lib/kunit/executor.c:140:10: fatal error:
executor_test.c: No such file or directory
  140 | #include "executor_test.c"
      |          ^~~~~~~~~~~~~~~~~

I just `git am` or something just really doesn't like executor_test.c :)
