The pressure notification added to the virtio-balloon driver by this series is going to be used by the host (QEMU, in this case) to implement automatic balloning support. More details in patch 3/4 and patch 4/4.
Patch 1/4 adds in-kernel vmpressure support and is not really part of this series, it's added here for the convenience of someone who wants to try automatic ballooning. Patch 2/4 is a hack to make in-kernel vmpressure work for something not related to cgroups, I'll improve it in later versions.
