Hi Paolo,

Thank you for your modifications, that's great!

Our CI (Cirrus) did some validations with a debug kernel and here is its report:

- KVM Validation: debug (except selftest_mptcp_join):
  - Critical: 1 Call Trace(s) ❌:
  - Task: https://cirrus-ci.com/task/6638955139956736
  - Summary: https://api.cirrus-ci.com/v1/artifact/task/6638955139956736/summary/summary.txt

- KVM Validation: debug (only selftest_mptcp_join):
  - Critical: 1 Call Trace(s) ❌:

If there are some issues, you can reproduce them using the same environment as
the one used by the CI thanks to a docker image, e.g.:

    $ cd [kernel source code]
    $ docker run -v "${PWD}:${PWD}:rw" -w "${PWD}" --privileged --rm -it \
        --pull always mptcp/mptcp-upstream-virtme-docker:latest \
        auto-debug

For more details:

Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)
