Yes, if you agree with Jeff's original point.
But I don't, actually. Sure, on some machines+workloads, AIO is more
common than sync IO. But I expect that when we sum across all the
machines+workloads in the world, sync IO is more common and is hence the
case we should optimise for.
That's assuming that the unlikely() actually does something.
For the record, I agreed with your counter-point, and retract[ed?] my
disagreement...
