[PATCH v13 QEMU 2/3] virtio-balloon: Add bit to notify guest of unused page reporting

Alexander Duyck
2019-11-05T22:06:53Z

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.
