[PATCH v4 0/1] mm: virtio-balloon fix to go through the -mm tree
@Andrew, as this fix is based on free page reporting, can this go through
your tree?
Patch #1 contains a proper description.
v3 -> v4:
- Add Ack from David Rientjes
- Minor tweaks to test details in the patch description
v2 -> v3:
- Use vb->vdev instead of vdev in all feature checks. We'll clean the
other ones up later.
- Add one empty line virtballoon_probe() to make it look
