Vitaly Kuznetsov 81988a0e6b storvsc: get rid of bounce buffer ... Storvsc driver needs to ensure there are no 'holes' in the presented sg list (all segments in the middle of the list need to be of PAGE_SIZE). When a hole is detected storvsc driver creates a 'bounce sgl' without holes and copies data over with copy_{to,from}_bounce_buffer() functions. Setting virt_boundary_mask to PAGE_SIZE - 1 guarantees we'll never see such holes so we can significantly simplify the driver. This is also supposed to bring us some performance improvement for certain workloads as we eliminate copying.
