Perhaps this should just be > "should_bug"? I used the name suggested by David Gow in the RFC Patch [1]. I believe "should_panic" is better because it directly matches the attribute name and will stay consistent in case the panic handler changes the way it trigger kernel panics (although this is very unlikely I think). That said, I'd be happy to change it to should_bug if that is preferred, please let me know what you think!
