Hello, David
If you don't mind, could you give me some advises about the sendpage mechanism.
I'd like to implenent sendpage of UDP stack which NFS uses heavily. It may improve the performance of NFS over UDP dramastically.
I wonder if there were "SENDPAGES" interface instead of sendpage between socket layer and inet layer, we could send some pages atomically with low overhead. And it could make implementing RPC over UDP easier to send multiple pages as one UDP pakcet easily.
How do you think about this approach?

OK.
