v3: Preserve backward compatibility with older kernels:
    - drop "lib/ktap: Drop workaround for missing top level KTAP headers",
      add "lib/ktap: Improve TODO workaround description" instead,
    - keep legacy processing patch when obtainig a list of test cases from
      kunit modules occurs not supported,
  - print debug message on pthread_kill() error once per loop (Mauro),
  - move "parent" field of the structure near other pthread_* type fields
    (Kamil),
  - drop unneeded explicit return from noop void function (Kamil),
  - if (!err) looks strange, add a comment (Kamil),
  - preserve a link to KTAP standard in a comment above the winning
    implementation of KTAP parser (Kamil).
v2: Add a new patch that provides all results cleanup helper,
  - split out changes in handling of modprobe errors and kernel taints from
    "Fetch a list of test cases in advance" to separate patches (Kamil),
  - prepare for KTAP parsing after modprobe completed in a separate
    patch,
  - drop other modprobe and kernel taint related changes from the series,
  - fix some string duplicates referenced from filtered out test cases not
    freed,
  - always pass last result to next dynamic sub-subtest, fetch first
    result right after loading the kunit test module for execution,
  - still break the loop of test cases on unexpected return codes from
    kunit_kmsg_get_result(),
  - fix typos (Kamil),
  - update commit descriptions.
