Um, so the stack unwinders use "does this look like a kernel address" because we omit the frame pointer? To keep that optimization, we add 220 non-trivial lines to module.c? Don't get me wrong, it's cute code, but I do wonder if at some point a grown up is going to come along and tell us to stop :) Cheers, Rusty. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
