search for: vring_create_virtqueue

vring_create_virtqueue() allows the caller to specify via the may_reduce_num parameter whether the vring code is allowed to allocate a smaller ring than specified. However, the split ring allocation code tries to allocate a smaller ring on allocation failure regardless of what the caller specified. This may cause troubl...

...fe9d ("virtio: Add improved queue allocation API") establishes a new way of allocating virtqueues (as a part of the effort that taught DMA to virtio rings). In the future we will want virtio-ccw to use the DMA API as well. Let us switch from the legacy method of allocating virtqueues to vring_create_virtqueue() as the first step into that direction.
