In the next patches where the worker can be killed while in use, we need to be able to take the worker mutex and kill queued works for new IO and flushes, and set some new flags to prevent new __vhost_vq_attach_worker calls from swapping in/out killed workers. If we are holding the worker mutex during a flush and the flush's work is still in the queue, the worker code that will handle the SIGKILL cleanup won't be able to take the mutex and perform it's cleanup. So this patch has us drop the worker mutex while waiting for the flush to complete.

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.
