Checked several modules which registered with reboot_notifier_list, the
passed string is not cared. Just curious, could you tell how you have
used or plan to use this string in your code?
No objection to this even though it's trivial if no real use case.

It’d be great if you answered Baoquan He’s question, how it’s actually
used in SONiC. (I just sent the patch upstream to reduce the out-of-tree
patches in SONiC.)
Kind regards,
Paul
