SubjectRe: elevator-starvation-4 (2.2.14 && 2.3.42)
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.
