Subject: [PATCH RFC 0/3] virtio: silence KCSAN warnings

When booting a Qemu VM whith KCSAN to debug filesystem races I
encountered a bunch of KCSAN splats in virtio.

I suspect them to be false positives.

I decided to send this as an RFC patchset, as I have no prior knowledge
of virtio.

Johannes Thumshirn (3):
  virtio: silence KCSAN warning in virtqueue_kick_prepare
  virtio: silence KCSAN warning in virtqueue_get_buf_ctx_split
  virtio: silence KCSAN warning in vring_interrupt
