what do you mean by that - which is this same resource?From what has been said here before, all futexes are stored in the same list or hash table or whatever it was. I want to see how that code behaves if many separate processes concurrently use futexes.
futexes are stored in the bucket hash, and these patches do not change that. The pi-list that was talked about is per-futex. So there's no change to the way futexes are hashed nor should there be any scalability impact - besides the micro-impact that was measured in a number of ways - AFAICS.
