Yes, this should apply cleanly to 4.14 as well. It won't apply to
pre-4.14 kernels because of the fine-grained locking changes, but the
same issue exists there and I suspect it would cause the same crash.
Do you want me to send a separate patch for pre-4.14?

Also, I'm going to send a v2 for this because it can be a bit cleaner
(avoiding a deref).

Thanks,
Martijn
