Subject: [PATCH v2 3/3] memory: Update description of memory_region_is_mapped()
Date: Tue, 26 Oct 2021 18:06:49 +0200	[thread overview]
Message-ID: <20211026160649.47545-4-david@redhat.com> (raw)
In-Reply-To: <20211026160649.47545-1-david@redhat.com>

Let's update the documentation, making it clearer what the semantics
of memory_region_is_mapped() actually are.
