net: skb_fclone_busy() needs to detect orphaned skb
Some drivers are unable to perform TX completions in a bound time. They instead call skb_orphan() Problem is skb_fclone_busy() has to detect this case, otherwise we block TCP retransmits and can freeze unlucky tcp sessions on mostly idle hosts. Signed-off-by: Eric Dumazet <edumazet@google.com> Fixes: 1f3279ae0c13 ("tcp: avoid retransmits of TCP packets hanging in host queues") Signed-off-by: David S. Miller <davem@davemloft.net>
