Hi, Well, yes and no. I guess my fundamental claim is that if userland is able to generate requests faster than the driver can fulfill them for an extended period of time then we've got a larger problem than worrying about a particular request taking a long time to satisfy. Indeed, I claim that as long as the driver cannot keep up there will always be a pathological case where a particular request is unreasonably delayed.
I'm not saying I have any idea what the correct solution is, but I feel that tackling the request scheduling problem is less meaningful if we haven't at least taken a whack at solving the request overrun problem.
Cheers, Bruce.
