| H A D | skbuff.c | a080e7bd Wed May 13 15:34:13 CDT 2015 Alexander Duyck <alexander.h.duyck@redhat.com> net: Reserve skb headroom and set skb->dev even if using __alloc_skb
When I had inlined __alloc_rx_skb into __netdev_alloc_skb and
__napi_alloc_skb I had overlooked the fact that there was a return in the
__alloc_rx_skb. As a result we weren't reserving headroom or setting the
skb->dev in certain cases. This change corrects that by adding a couple of
jump labels to jump to depending on __alloc_skb either succeeding or failing.
Fixes: 9451980a6646 ("net: Use cached copy of pfmemalloc to avoid accessing page")
