Hi,
as Jason suggested some months ago, I looked better at the virtio-net driver to
understand if we can reuse some parts also in the virtio-vsock driver, since we
have similar challenges (mergeable buffers, page allocation, small
packets, etc.).
Initially, I would add the skbuff in the

Replace virtqueue_kick by virtqueue_kick_prepare, which requires
serialization, and virtqueue_notify, which does not. Repurpose the
return values to indicate whether the vq should be notified.
This fixes a lock contention with qemu host. When the guest calls
vibad rtqueue_notify, the qemu vcpu

Replace virtqueue_kick by virtqueue_kick_prepare, which requires
serialization, and virtqueue_notify, which does not. Repurpose the
return values to indicate whether the vq should be notified.
This fixes a bad spinlock contention when the host is qemu. When
the guest calls virtqueue_notify, the
