Here are a few patches linked to the 'set-flags' interface with the
in-kernel path-manager.

Patch 1: a small cleanup. For -next.

Patch 2: a small optimisation not to iterate over all subflows to do
         nothing. For -next.

Hi Matthieu,

Thank you for your modifications, that's great!

Our CI did some validations and here is its report:

- KVM Validation: normal: Success! ✅

Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=927547


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 ;-)
