__vhost_vq_attach_worker uses the vhost_dev mutex to serialize the swapping of a virtqueue's worker. This was done for simplicity because we are already holding that mutex. In the next patches where the worker can be killed while in use, we need finer grained locking because some drivers will hold the vhost_dev mutex while flushing. However in the SIGKILL handler in the next patches, we will need to be able to swap workers (set current one to NULL), kill queued works and stop new flushes while flushes are in progress. To prepare us, this has us use the virtqueue mutex for swapping workers instead of the vhost_dev one.

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.
