A kitchen-sink kernel might take up that much space, but you can build a minimal embedded kernel that only takes up ~200k, at which point 2.6k represents a >1% decrease. Add a few more changes like this, and those decreases start to add up. At this point, no one thing you can chop out of the kernel will give you a 100k decrease by itself; you need a pile of changes like this one to do that. - Josh Triplett -- 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/
