Subject: [PATCH v15 QEMU 2/3] virtio-balloon: Add bit to notify guest of unused page reporting
Date: Thu, 05 Dec 2019 08:24:22 -0800	[thread overview]
Message-ID: <20191205162422.19737.57728.stgit@localhost.localdomain> (raw)
In-Reply-To: <20191205161928.19548.41654.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.
