[UM]: Fix use of skb after netif_rx
Recently, Wang Chen submitted a patch
(d30f53aeb31d453a5230f526bea592af07944564) to move a call to netif_rx(skb)
after a subsequent reference to skb, because netif_rx may call kfree_skb on
its argument. The same problem occurs in some other drivers as well.
This was found using the following semantic match.
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
expression skb, e,e1;
@@
(
netif_rx(skb);
|
netif_rx_ni(skb);
)
... when != skb = e
(
skb = e1
|
* skb
)
