Reconnect worker currently assumes that the server struct is alive and only takes reference on the server if it needs to call smb2_reconnect. With the new ability to disable channels based on whether the server has multichannel disabled, this becomes a problem when we need to disable established channels. While disabling the channels and deallocating the server, there could be reconnect work that could not be cancelled (because it started). This change forces the reconnect worker to unconditionally take a reference on the server when it runs. Also, this change now allows smb2_reconnect to know if it was called by the reconnect worker. Based on this, the cifs_put_tcp_session can decide whether it can cancel the reconnect work synchronously or not.

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.
