Look for the udev generated persistent device name for NVMe devices in addition to the SCSI ones and the Redhat-specific device mapper name. This is the client side implementation of RFC 9561 "Using the Parallel NFS (pNFS) SCSI Layout to Access Non-Volatile Memory Express (NVMe) Storage Devices". Note that the udev rules for nvme are a bit of a mess and udev will only create a link for the uuid if the NVMe namespace has one, and not the NGUID. As the current RFCs don't support UUID based identifications this means the layout can't be used on such namespaces out of the box. A small tweak to the udev rules can work around it, and as the real fix I will submit a draft to the IETF NFSv4 working group to support UUID-based identifiers for SCSI and NVMe.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
