Hi Jakub,

I originally submitted to security@...nel.org on Dec 27th and this submission was a direct request from the maintainers. So if your concern is whether or not they are tracking, I can confirm that they are. If it's just a matter of adherence to process, than I will go ahead and do it, but wanted to avoid the churn if unnecessary. 

The big question currently is what is appropriate for stable. I do not believe it's possible to fix this issue without negatively impacting the performance of the gate without either using a unlock → cancel → relock pattern or conversion to RCU. Neither of which is ideal for stable, so more constructive input is needed.

Thanks
Paul
