A virtio_balloon's parent device may be configured so that a configuration change interrupt is a wakeup event. Extend the processing of such a wakeup event until the balloon finishes inflating or deflating by calling pm_stay_awake/pm_relax in the virtio_balloon driver. Note that these calls are no-ops if the parent device doesn't support wakeup events or if the wakeup events are not enabled. This change allows the guest to use system power states such as s2idle without running the risk the virtio_balloon's cooperative memory management becoming unresponsive to the host's requests.

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.
