I have asked stable maintainers upstream, and it got queued for the
6.12.y stable series:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/commit/?id=7294cf6ff42482531f62f9b2a74d9c7ee00bbb59

I'm not reassigning the bug to src:linux as I think the cifs-utils
might need to handle such situation more gracefully? I.e. usually we
cannot across packages in distribution guarantee such a lockstep
update.

cifs-uitls maintainers, might that be something which can be handled
on both sides? At least for upstream 6.12.y should look good now per
se.
