As part of that I also removed the strange EOPNOTSUPP ignore, but Mike reverted it just because it changed something in the dm testsuite. I still believe we should never ignore it in this helper, and only do so in callers that believe it's the right thing. -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
