[Qemu-devel] [PATCH v2 0/2] nbd: Async built-in server negotiation

[Fam Zheng]

v2: Adopt Daniel and Paolo's idea: always call close_fn.

During nbd_send_negotiate, if the client simply doesn't respond, the function
will not return, and the whole event loop is blocked.

Make the I/O effectively asynchronous by using coroutine read/write, so that a
malicious or disappeared client cannot make a hang.
