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.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
