Subject: [PATCH v12 QEMU 2/3] virtio-balloon: Add bit to notify guest of unused page reporting
Date: Tue, 22 Oct 2019 15:29:31 -0700	[thread overview]
Message-ID: <20191022222931.17594.85842.stgit@localhost.localdomain> (raw)
In-Reply-To: <20191022221223.17338.5860.stgit@localhost.localdomain>

From: Alexander Duyck <alexander.h.duyck@linux.intel.com>

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.
