[PATCH v1 0/6] mm / virtio-mem: support ZONE_MOVABLE
Currently, virtio-mem does not really support ZONE_MOVABLE. While it allows to online fully plugged memory blocks to ZONE_MOVABLE, it does not allow to online partially-plugged memory blocks to ZONE_MOVABLE and will never consider such memory blocks when unplugging memory. This might be surprising for users (especially, if onlining suddenly fails). Let's support partially plugged memory
