I do not see how one can effectively use skb_insert() without holding some kind of lock. Otherwise other cpus could have changed the list right before we have a chance of acquiring list->lock. Only existing user is in drivers/infiniband/hw/nes/nes_mgt.c and this one probably meant to use __skb_insert() since it appears nesqp->pau_list is protected by nesqp->pau_lock. This looks like nesqp->pau_lock could be removed, since nesqp->pau_list.lock could be used instead.
