Sure Helge, I guess I can do that - will resubmit for V2.

But notice the patch is self-contained, as it fixes a current issue in
the code - the risk for a lockup due to spinlock taking on atomic
context. It doesn't require the panic refactor to be merged in order to
achieve its goal...

I agree that such issue is rare to trigger though, so definitely no
hurry is needed =)

Cheers,
