Commit 7a1b3490f47e ("mptcp: don't account accept() of non-MPC client as fallback to TCP") does not apply to the 6.8-stable tree. That's because there are some conflicts with recent refactoring done in the selftests:
- commit e3aae1098f10 ("selftests: mptcp: connect: fix shellcheck warnings") - commit e7c42bf4d320 ("selftests: mptcp: use += operator to append strings")
These two patches look harmless, probably safer and easier to backport them, than diverging even more from the development branch.
Note that all these three commits have been backported without conflicts.
