when starting error recovery there might be a authentication work running, and it involves I/O commands. Given the controller is tearing down there is no chance for the I/O to complete other than timing out which may unnecessarily take a full io timeout. So first tear down the queues, fail/cancel all inflight I/O (including potentially authentication) and only then stop authentication. This ensures that failover is not stalled due to blocked authentication I/O.

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.
