The dax is only supported on pfn type pmem devices since commit
f467fee48da4 ("block: move the dax flag to queue_limits"). Trying
to mount DAX filesystem fails with this error:
mount: : wrong fs type, bad option, bad superblock on /dev/pmem7,
missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.
dmesg: EXT4-fs (pmem7): DAX unsupported by block device.
Fix the problem by adding dax flag setting for the missed case.
Fixes: f467fee48da4 ("block: move the dax flag to queue_limits")

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.
