If @server->tcpStatus is set to CifsNeedReconnect after acquiring @ses->session_mutex in smb2_reconnect() or cifs_reconnect_tcon(), it means that a concurrent thread failed to negotiate, in which case the server is no longer responding to any SMB requests, so there is no point making the caller retry the IO by returning -EAGAIN. Fix this by returning -EHOSTDOWN to the callers on soft mounts.

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 reStructuredText 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.
