Remove the assumption that the skbs that make it to netpoll_send_skb_on_dev are allocated with find_skb, such that skb->users == 1 and nothing is attached that would prevent the skbs from being freed from hard irq context. Remove this assumption by replacing __kfree_skb on error paths with dev_kfree_skb_irq (in hard irq context) and kfree_skb (in process context). Signed-off-by: "Eric W.
