[PATCH vhost v9 03/12] virtio_ring: check use_dma_api before unmap desc for indirect

Inside detach_buf_split(), if use_dma_api is false, vring_unmap_one_split_indirect will be called many times, but actually nothing is done. So this patch check use_dma_api firstly. Signed-off-by: Xuan Zhuo --- drivers/virtio/virtio_ring.c | 6 -- 1 file changed, 4 insertions(+), 2 deletions(
