Because it's VM_BUG_ON instead of BUG_ON, I don't think it's something
we are likely to see triggered on stable kernels. It is worth
introducing a VM_WARN_ON do you think to catch really bad callers, ones
where it is not advisory?

Whether such a helper was introduced or not though, this does fix a real
problem so;
