[RFC PATCH 0/4] virtio_balloon: add pressure notification via a new virtqueue

From: Luiz Capitulino
Date: Thu Jan 16 2014 - 11:24:53 EST

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.

Glauber Costa (1):
vmpressure: in-kernel notifications

Luiz capitulino (3):
vmpressure in-kernel: hack
virtio_balloon: add pressure notification via a new virtqueue
virtio_balloon: skip inflation if guest is under pressure
