The nvme driver sets up the size of the nvme namespace in two steps. First it initializes the device with standard logical block and metadata sizes, and then sets the correct logical block and metadata size. Due to the OCSSD 2.0 specification relies on the namespace to expose these sizes for correct initialization, let it be updated appropriately on the LightNVM side as well.
