I would be surprised if it didn't apply to net-next.

I would be surprised if an automatic merge did not produce correct code
here, as I specifically replaced the implementation of the macro with
an instance of the new macro and adjusted semantics on purpose. If it
compiles, it's correct.

Would you still prefer for me to re-send this patch based against
net-next once the new macro is merged and within net-next?
