Hi Xu Qiang, first of all, thanks for your patch!
I'd like to mention 2 things about it:

(a) As-is, there's no much use for it - I mean, you're adding a helper
but you didn't change the uses of such notifier list addition (and there
are plenty of them). Are you intend to change it, or just use the new
API in new calls?

(b) Even more important: we are working in a panic notifier refactor
[0], and that'll add new lists. I'm still working on that, plan to
submit (relatively) soon. Maybe worth to wait it, if this one is not urgent?

Cheers,


Guilherme
