I think something like
/sys/class/misc/debug/panic_notifier/ipmi/priority
/sys/class/misc/debug/panic_notifier/watchdog/priority
/sys/class/misc/debug/panic_notifier/kdb/priority
/sys/class/misc/debug/panic_notifier/kdump/priority
would be better. It's more self-describing if you want to change the
order.
