The flush after vhost_dev_cleanup is not needed because: 1. It doesn't do anything. vhost_dev_cleanup will stop the worker thread so the flush call will just return since the worker has not device. 2. It's not needed for the re-queue case. vhost_scsi_evt_handle_kick grabs the mutex and if the backend is NULL will return without queueing a work. vhost_scsi_clear_endpoint will set the backend to NULL under the vq->mutex then drops the mutex and does a flush. So we know when vhost_scsi_clear_endpoint has dropped the mutex after clearing the backend no evt related work will be able to requeue. The flush would then make sure any queued evts are run and return.

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.
