I'm still not used to these lists that set the 'reply-to' header, so I don't get a reply explicitly addressed to me.... I've have to make my filters smarter! Does DM *always* use small bios? Even for multipath targets, where presumably there would be no need even to limit the size? If so, I guess this patch isn't going to make a big difference no, but it would be worth having it in place for whenever handling larger bios gets implemented.
