If you print 100 lines (or 1000) in 5 seconds, then you just stopped printing from that context for 59 minutes and 55 seconds. That's a long time to block printing. What happens if you had a couple of NMIs go off that takes up that time, and then you hit a bug 10 minutes later from that context. You just lost it. This is a magnitude larger than any other user of rate limit in the kernel. The most common time is 5 seconds. The longest I can find is 1 minute. You are saying you want to block printing from this context for 60 minutes! That is HUGE! I don't understand your rational for such a huge number. What data do you have to back that up with? -- Steve
