Haven't looked that deep, but it seems to involve a tunneling device,
so I wonder whether it's gonna be fixed by:
- https://patchwork.kernel.org/project/netdevbpf/patch/20250312190513.1252045-2-sdf@xxxxxxxxxxx/
- https://patchwork.kernel.org/project/netdevbpf/patch/20250312190513.1252045-3-sdf@xxxxxxxxxxx/

Do you have a repro? Can you rerun with the above fixes and enable
lockdep?
