I wonder if there is anything out there actually using vmsplice. It seems extremely hard to use facility anyways. And playing games with MMU with all the evil lock contention troubles, seems like asking for trouble as well.

I hope kernel devs added automated tests for all these issues, and that those tests are run frequently. That's the first thing I do when trying to unpick a complicated mess like this.
