[Qemu-block] [PATCH v2 2/2] virtio-blk: reject configs with logical block size > physical block size

2017-12-11 Thread Mark Kanda
virtio-blk logical block size should never be larger than physical block size because it doesn't make sense to have such configurations. QEMU doesn't have a way to effectively express this condition; the best it can do is report the physical block exponent as 0 - indicating the logical block size
