Bug description:
SRU Justification
[Impact]
Google requested that the virtio_balloon module be made loadable,
rather than built-in. This is to support disabling the module at
runtime, which is specified as possible in their documentation:
https://cloud.google.com/compute/docs/dynamic-resource-
management#disabling_the_virtio_memory_balloon_device
[Fix]
Change CONFIG_VIRTIO_BALLOON to build the driver as a loadable module
rather than a built-in, drivers/virtio/* is already in the inclusion
list, so the driver will be included in the main modules package.
[Test Plan]
List files in the linux-modules package and verify that
virtio_balloon.ko is there.
[Regression potential]
The regression potential is very low since the module will still be
included with all cloud installations and a user has to manually
disable it to get different behavior.
