Subject: [PATCH v2 6/7] xen/balloon: try to merge system ram resources
Date: Tue, 8 Sep 2020 22:10:11 +0200 [thread overview]
Message-ID: <20200908201012.44168-7-david@redhat.com> (raw)
In-Reply-To: <20200908201012.44168-1-david@redhat.com>
Let's try to merge system ram resources we add, to minimize the number
of resources in /proc/iomem. We don't care about the boundaries of
individual chunks we added.
