Indeed, that's odd. Do you use a different merge strategy?

I just tried on my side with the default merge strategy coming with Git
2.43.0, and it works:

  $ git fetch
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
refs/heads/linux-6.6.y
  $ git switch -c tmp FETCH_HEAD
  $ git rebase -i 2f39e4380e73~ ## to drop these 3 patches you added:
    # 2f39e4380e73 selftests: mptcp: connect: fix shellcheck warnings



    # bd3b5b0fff75 mptcp: don't overwrite sock_ops in mptcp_is_tcpsk()



    # f723f9449193 mptcp: don't account accept() of non-MPC client (...)
  $ git cherry-pick -xs \
    629b35a225b0 e3aae1098f10 e7c42bf4d320 8e2b8a9fa512 7a1b3490f47e
  Auto-merging tools/testing/selftests/net/mptcp/mptcp_join.sh
  (...)
  $ echo $?
  0

But if I try the 3 patches you selected

  $ git reset --hard HEAD~5
  $ git cherry-pick -xs e3aae1098f10 8e2b8a9fa512 7a1b3490f47e
  Auto-merging tools/testing/selftests/net/mptcp/mptcp_connect.sh
  (...)
  CONFLICT (content): Merge conflict in
tools/testing/selftests/net/mptcp/mptcp_connect.sh
  error: could not apply 7a1b3490f47e... mptcp: don't account accept()
of non-MPC client as fallback to TCP


And the conflict makes sense: with the version that is currently in
linux-6.6.y branch, the new check is done after having printed "OK", so
that's not correct.


I can share the 5 patches I applied without conflicts on top of the
current linux-6.6.y branch, without the 3 patches you added today if it
can help.

Thank you!

Cheers,
Matt
