Subject: virtio_ring: split: stop __vring_new_virtqueue as export symbol
X-Git-Tag: v6.6.17~6796^2~71
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=07d9629d49584b6f79faa6158cd7aef7e6919703;p=platform%2Fkernel%2Flinux-rpi.git

virtio_ring: split: stop __vring_new_virtqueue as export symbol

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.
