This DM multipath NVMe bio-based support requires CONFIG_NVME_MULTIPATH to not be set. In the future hopefully NVMe multipath and DM multipath can co-exist more seemlessly. But as is, if CONFIG_NVME_MULTIPATH=Y then all the individal NVMe paths will remain hidden to upper layers and as such DM multipath will not be able to manage them. Though NVMe's native multipathing doesn't multipath namespaces across subsystems; so technically a user _could_ use CONFIG_NVME_MULTIPATH=Y and also use DM multipath to multipath across subsystems.
