Or maybe have two lists of panic notifiers, the safe and the destructive
list. So in case of fake panic, we can only call the safe notifiers.
I tried something like that:

The second question is how to simulate a panic context in a
non-destructive way, so we can test the panic notifiers in CI, without

Hi,
While writing a panic handler for drm devices [1], I needed a way to
test it without crashing the machine.
So from debugfs, I called
atomic_notifier_call_chain(&panic_notifier_list, ...), but it has the
side effect of calling all other panic notifiers registered.
So Sima suggested to mov
