This version makes the disk stats on struct gendisk per-cpu. I am working on making the per partition stats per-cpu too (struct hd_struct).
In general I'm in favor of this. It seems intuitive to me that counters of this type should be per-cpu. But the question is, do we actually see any gains? At the very least, are we sure we've not introduced any degradation? Has any of your testing so far been measuring performance or just checking for correctness?
