Subject: [PATCH v10 QEMU 2/3] virtio-balloon: Add bit to notify guest of unused page reporting
Date: Wed, 18 Sep 2019 10:53:50 -0700	[thread overview]
Message-ID: <20190918175350.23606.70808.stgit@localhost.localdomain> (raw)
In-Reply-To: <20190918175109.23474.67039.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.
