So? Even if we hadn't had this bug before (we have), your argument is
utter crap. Even if we weren't to have that patter right *now*, that
doesn't mean that it cannot happen.
Your grep is also not at all exhaustive. What if somebody does
printk("%s.."
how are you going to prove that '%s' doesn't contain a level marker
thing? It's much easier to just say "use a KERN_CONT" (or more
commonly KERN_DEFAULT) to avoid the problem.
We do need an escape model. The current KERN_CONT does that. Stop
arguing for crap.
