Doing range flushes is not the answer. It is going to be about the same cost as doing per-page flushes.
The cost is doing the cross calls at all, not the granularity in which we do them.
You're refusing to do any work to prove whether your case matters at all in real life, and you're calling other people assholes for asking that you do so.
Franks a lot, David S. Miller davem@redhat.com
