Here is my last series of the year :)

There are two fixes with their tests:

- a subflow closed event can be visible multiple times, see issue #603

- the subflow closed event didn't contain the error as expected.

The 4 first patches are for -net, the rest are small fixes and
improvements for net-next. Some tests should be quicker now.

Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=1036645


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-normal

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 ;-)
