net: Fix skb_update_prio RCU usage.
Change function rcu_dereference to rcu_dereference_bh to avoid warning [ INFO: suspicious RCU usage. ] ------------------------------- net/core/dev.c:2459 suspicious rcu_dereference_check() usage! because we are locking with rcu_read_lock_bh(); in function dev_queue_xmit(struct sk_buff *skb) Signed-off-by: Igor Maravic <igorm@etf.rs> Signed-off-by: David S.
