Subject: [virtio-dev] [PATCH v8 QEMU 2/3] virtio-balloon: Add bit to notify guest of unused page reporting
Date: Fri, 06 Sep 2019 07:54:43 -0700 [thread overview]
Message-ID: <20190906145443.574.8266.stgit@localhost.localdomain> (raw)
In-Reply-To: <20190906145213.32552.30160.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.
