The reset_work waits for queued IO to complete before setting the controller to live. If any of these times out and requeues, we won't be able to restart the controller because the reset_work is already running. Flush all entered requests to a failed completion if a timeout occurs in the connecting state, and ensure the controller can't transition to the live state after we've unblocked it from waiting for completions.

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.
