[ Upstream commit8730c1ddb6] When tearing down a controller the following warning is issued: WARNING: CPU: 0 PID: 30681 at ../kernel/workqueue.c:2418 check_flush_dependency This happens as the err_work workqueue item is scheduled on the system workqueue (which has WQ_MEM_RECLAIM not set), but is flushed from a workqueue which has WQ_MEM_RECLAIM set. Fix this by providing an FC-NVMe specific workqueue.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
