[v14,07/42] virtio_ring: split: stop __vring_new_virtqueue as export symbol

Commit Message

Xuan Zhuo Aug. 1, 2022, 6:38 a.m. UTC

There is currently only one place to reference __vring_new_virtqueue()
directly from the outside of virtio core. And here vring_new_virtqueue()
can be used instead.

Subsequent patches will modify __vring_new_virtqueue, so stop it as an
export symbol for now.
