With this new option, qemu-img bench can be told to advance the current offset after each request by a different value than the buffer size. This is useful for controlling the conditions for cluster allocation in image formats (e.g. qcow2 cluster allocation with COW in front of the request, or COW areas that aren't overwritten immediately).
