Subject: [PATCH net 0/3] mptcp: sched: fix some lock issues

Two small fixes related to the MPTCP packets scheduler:

- Patch 1: add missing rcu_read_(un)lock(). A fix for >= 6.6.

- Patch 2: remove unneeded lock when listing packets schedulers. A fix
  for >= 6.10.

And some modifications in the MPTCP selftests:

- Patch 3: a small addition to the MPTCP selftests to cover more code.
