virtio_ring: introduce add api for premapped
Two APIs are introduced to submit premapped per-buffers.
int virtqueue_add_inbuf_premapped(struct virtqueue *vq,
struct scatterlist *sg, unsigned int num,
void *data,
void *ctx,
gfp_t gfp);
int virtqueue_add_outbuf_premapped(struct virtqueue *vq,
struct scatterlist *sg, unsigned int num,
void *data,
gfp_t gfp);
