Subject: [PATCH v3 7/7] hv_balloon: try to merge system ram resources
Date: Thu, 10 Sep 2020 11:13:40 +0200 [thread overview]
Message-ID: <20200910091340.8654-8-david@redhat.com> (raw)
In-Reply-To: <20200910091340.8654-1-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.
