Subject: [PATCH v14 QEMU 2/3] virtio-balloon: Add bit to notify guest of unused page reporting
Date: Tue, 19 Nov 2019 13:54:52 -0800 [thread overview]
Message-ID: <20191119215452.25688.88059.stgit@localhost.localdomain> (raw)
In-Reply-To: <20191119214454.24996.66289.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.
