Set vdpa device suspended state on successful suspend. Clear it on successful resume and reset. The state will be locked by the vhost_vdpa mutex. The mutex is taken during suspend, resume and reset in vhost_vdpa_unlocked_ioctl. The exception is vhost_vdpa_open which does a device reset but that should be safe because it can only happen before the other ops.

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.
