Drain async IO on the hw side
This patch makes sure that async IO has completed drained from the device queue before starting sync IO. Hopefully that should make things as good as disabling NCQ, and it should even improve the situation without NCQ.
I'd like for people to test this patch and see if it makes a difference. It's against 2.6.31-rc (ish), but I _think_ it will apply against 2.6.30 as well. If not, holler, and I'll do a backport too.
