tools/virtio: remove smp_read_barrier_depends()

2022-12-28T10:28:11Z

This gets rid of the last references to smp_read_barrier_depends() which for the kernel side was removed in v5.9. The serialization required for Alpha is done inside READ_ONCE() instead of having users deal with it. Simply use a full barrier, the architecture does not have rmb in the first place.

tools/virtio: initialize spinlocks in vring_test.c

2022-12-28T10:09:47Z

The virtio_device vqs_list spinlocks must be initialized before use to prevent functions that manipulate the device virtualqueues, such as vring_new_virtqueue(), from blocking indefinitely.

virtio_ring: split: stop __vring_new_virtqueue as export symbol

2022-08-11T08:06:38Z

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.
