Sure, I was in fact implying its not the end of the world, although it will be interesting to see the impact on different (non pathological) workloads, even if it only affects a single waiter. Also, technically this issue can also affect rwsems if only using writers, but that's obviously pretty idiotic, so I wouldn't worry about it.
Thanks, Davidlohr
