[PATCH v5 QEMU 2/3] virtio-balloon: Add bit to notify guest of unused page reporting

From: Alexander Duyck
Date: Mon Aug 12 2019 - 17:34:43 EST


From: Alexander Duyck <alexander.h.duyck@xxxxxxxxxxxxxxx>

Add a bit for the page reporting feature provided by virtio-balloon.

This patch should be replaced once the feature is added to the Linux kernel
and the bit is backported into this exported kernel header.
