Subject: [PATCH net-next 09/12] tools/virtio: switch to __ptr_ring_empty
Date: Fri, 26 Jan 2018 01:36:39 +0200	[thread overview]
Message-ID: <1516923320-16959-12-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1516923320-16959-1-git-send-email-mst@redhat.com>

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