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 and around the 'accept()' code:
- commit 629b35a225b0 ("selftests: mptcp: display simult in extra_msg") - commit e3aae1098f10 ("selftests: mptcp: connect: fix shellcheck warnings") - commit e7c42bf4d320 ("selftests: mptcp: use += operator to append strings" - commit 8e2b8a9fa512 ("mptcp: don't overwrite sock_ops in mptcp_is_tcpsk()")
These 4 patches look harmless, probably safer and easier to backport them, than diverging even more from the development branch.
Note that applied in this order, all these 5 patches have been backported without conflicts. Tests are still OK.
