No difference. I just have to do it at some point. I can't work on this every day and when it comes to kernel, I'm a complete newbie. So things will take time. If people want that I fix this before mmiotrace goes into mainline, then so be it. blktrace, thanks for the hint, I should take a look at that. -- Pekka Paalanen http://www.iki.fi/pq/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
