[Nbd] how does NBD handle disconnections?

[Tomasz Chmielewski <mangoo@...119...>]

How does NBD handle disconnections?

For example, we have a nbd device mounted on a client, the client 
writes, and we kill a server for 15 minutes.

What will the client do?

Will the process accessing the nbd disk just freeze for 15 minutes 
(waiting for IO), and happily continue once nbd client can reconnect to 
the server?

Or perhaps something else will happen (kernel: device offlined/removed 
etc.)?
