[Nbd] For help, about kernel NBD driver

["edelweiss_zf3842" <edelweiss_zf3842@...787...>]

Hello!

I'm a Chinese student, doing my graduation project at Tsinghua University.
I really want to know the mechanism of NBD at kernel-level, such as:

1. How does the client get data from server (in detail) in order to use the remote block device?
2. What should I do if I want to make client get data from localhost instead of remote server
when client has already gotten those data from server and saved them on local disk?

Thanks a lot!
