We have a customer who reported the same issue recently, has there been
any development?

I don't see anything in either uvc nor v4l2 that would address the race
since this mail half a year ago (well, I could have missed it ;))


If nothing happened I'll probably backport this series as well, at which
point it might make more sense to take it in until a better fix gets
here then revert it...
