This sounds good, I already switch blkg allocation just before submit_bio() in some cases in this set. Just one question, for nowait case, is it correct that we still can't sleep during submit_bio()? If so, I still need to add nowait special case during blkg creation. Or I can just return -AGAIN if blkg lookup failed, this is much simplier. > -- Thanks, Kuai
