async already provides mechanisms to solve the above problem. This
doesn't have to be an either-or thing. I still don't get why we
aren't converting drivers properly over to async so that they still
follow the ordering rules where necessary. What's wrong with just
blacklisting the ones which can't follow ordering rules for now and
lifting the blacklist as they get fixed? That'd provide a gradual
transition path with the matching incentive for converting the drivers
while not disturbing userland.
Thanks.
