Using the netfilter xt-SYSRQ code seems to store the entered code and
execute it later after the system has returned to a normal state....
which is much too late to be useful.
    

So add a feature that allows xt-SYSRQ to not queue the request
and instead execute it immediately in softirq context.

I don't see what the big deal is.
  

I'm not familiar with the netfilter code and was about to ask some other
colleagues about it ... but I think you answered my main question which
was "does netfilter do things in interrupt context?"
