I thought about it carefully. Indeed, in my scenario(virtual machine which use
optane as DRAM), device assignment can be performed in userspace at very
early time after the system is started. This patch is not needed in my
scenario. Thank you for your reply.

Hi Zhenguo,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on linus/master]
[also build test ERROR on v5.17-rc6 next-20220225]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
device_dax driver always match dax devices by default. The other
drivers only match devices by dax_id. There are situations which
need kmem drvier match all the dax device at boot time. So
adding a parameter to support this function.
