Subject: tools/virtio: switch to __ptr_ring_empty
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=30f1d370744cc35f26d78a1dd31aeb0e4be93c38;p=openwrt%2Fstaging%2Fblogic.git

tools/virtio: switch to __ptr_ring_empty

We don't rely on lockless guarantees, but it
seems cleaner than inverting __ptr_ring_peek.
