We don't rely on lockless guarantees, but it seems cleaner than inverting __ptr_ring_peek. Signed-off-by: Michael S.

[PATCH net-next V3 0/6] switch to use tx skb array in tun
Hi all: This series tries to switch to use skb array in tun. This is used to eliminate the spinlock contention between producer and consumer. The conversion was straightforward: just introdce a tx skb array and use it instead of sk_receive_queue. A minor issue is to keep the tx_queue_len behaviour, since tun used to use it for the length of sk_receive_queue. This is done through: - add the
