Cong, i was not againest what you said as a techinical issue.
definitely, it can be a /proc, it is also able to be /sys if you like.
/proc is probably better than /dev from the original design thinking in kernel.

here i focused on people have this module to test CMA at runtime. i
also thought Michal also wants this module to show people the usage of
CMA as well.

i'll much appreciate if you have time to move it to /proc.
