very nit: if we're fixing the "doulbe" typo, can we also do
  "the doulbe" => "double" (drop the "the")

Thanks!
I can't believe we never noticed the duplicate `if not success` blocks
before now.

Some minor suggestions below if we're already going to send a v2 out for typos.

nit: perhaps we can shorten this to one line, i.e.
  return KunitResult(status, config_end - config_start)

Oh huh, I guess this duplication comes from commit 45ba7a893ad8
("kunit: kunit_tool: Separate out config/build/exec/parse")

@@ -64,78 +84,167 @@ def run_tests(linux: kunit_kernel.LinuxSourceTree,

ditto here,
  return KunitResult(status, build_end - build_start)
