Subject: [PATCH net-next 07/12] skb_array: use __ptr_ring_empty
Date: Fri, 26 Jan 2018 01:36:36 +0200 [thread overview]
Message-ID: <1516923320-16959-8-git-send-email-mst@redhat.com> (raw)
In-Reply-To: <1516923320-16959-1-git-send-email-mst@redhat.com>
__skb_array_empty should use __ptr_ring_empty since that's the only
legal lockless function.
