This particular patch? No. As for the whole series, Jens has done the
best actual benchmarks; mostly I've just been looking at profiles - I
don't have any high end hardware with drivers suitable for that kind of
benchmarking, myself.

Also, my changes have been particularly aimed at improving the situation
where an ioctx is shared between different threads; we don't have any
actual benchmarks for how much that's improved as fio doesn't do that
but the gains there are going to be much more significant, for
applications where that's useful.
