Hou Pu d970958b2d nbd: enable replace socket if only one connection is configured 
Nbd server with multiple connections could be upgraded since
560bc4b (nbd: handle dead connections). But if only one conncection
is configured, after we take down nbd server, all inflight IO
would finally timeout and return error. We could requeue them
like what we do with multiple connections and wait for new socket
in submit path.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
