As veth_xdp_rcv_skb() no-longer steals SKB data and no-longer uses XDP native xdp_do_redirect(), then it is possible to handle more types of SKBs with other memory types. Replacing skb_head_is_locked() with skb_cloned(). Signed-off-by: Jesper Dangaard Brouer <hawk@kernel.org> --- drivers/net/veth.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
