After seeking time on testing today upstream fsdax, I found it
actually doesn't work well as below:
[ 186.492983] ------------[ cut here ]------------
[ 186.493629] WARNING: CPU: 1 PID: 205 at fs/iomap/iter.c:33 iomap_iter+0x2f6/0x310
The problem is that m_dax_part_off should be applied to physical
addresses and very sorry about that I didn't catch this eariler.
Anyway, let's fix it up now. Also, I need to find a way to set up
a standalone testcase to look after this later.

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 Restructured Text 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.
