Subject: [PATCH v1 05/12] memory-device: Move memory_device_check_addable() directly into memory_device_pre_plug()
Date: Wed, 27 Oct 2021 14:45:24 +0200	[thread overview]
Message-ID: <20211027124531.57561-6-david@redhat.com> (raw)
In-Reply-To: <20211027124531.57561-1-david@redhat.com>

Move it out of memory_device_get_free_addr(), which is cleaner and
prepares for future changes.
