Subject: [PATCH v1 02/15] kvm: Add stub for kvm_get_max_memslots()
Date: Fri, 16 Jun 2023 11:26:41 +0200	[thread overview]
Message-ID: <20230616092654.175518-3-david@redhat.com> (raw)
In-Reply-To: <20230616092654.175518-1-david@redhat.com>

We'll need the stub soon from memory device context.

While at it, use "unsigned int" as return value and place the
declaration next to kvm_get_free_memslots().
