This change will reduce performance as we no longer have an overlap
between the next request starting to be dealt with in the hardware
vs the previous request being completed.  Your commit log doesn't
say _why_ the change is being made, it merely tells us what the
patch is doing, which we can see already.

Please describe changes a little better.
