Subject: [PATCH net-next v2 0/8] mptcp: various small and unrelated
 improvements

Here are various unrelated patches:

- Patch 1: sched: remove unused structure.

- Patch 2: sched: split the validation part, a preparation for later.

- Patch 3: pm: clarify code, not to think there is a possible UaF.
  Note: a previous version has already been sent individually to Netdev.

- Patch 4: subflow: simplify subflow_hmac_valid by passing subflow_req.

- Patch 5: mib: add counter for MPJoin rejected by the PM.

- Patch 6: selftests: validate this new MPJoinRejected counter.

- Patch 7: selftests: define nlh variable only where needed.

- Patch 8: selftests: show how to use IPPROTO_MPTCP with getaddrinfo.
  Note: a previous version has already been sent individually to Netdev.
