This caused a crash, right? Can you please include what can trigger such oops and how it looks like and reference to the original bug report. In general, when you're cc'ing stable, please try to provide as much information about the bug as possible so that downstreams have easier time evaluating the importance and risk of the change. The same goes for the previous patch.
