    [IPV4]: Replace __in_dev_get with __in_dev_get_rcu/rtnl · e5ed6399
    Herbert Xu 提交于
    The following patch renames __in_dev_get() to __in_dev_get_rtnl() and
    introduces __in_dev_get_rcu() to cover the second case.
    
    1) RCU with refcnt should use in_dev_get().
    2) RCU without refcnt should use __in_dev_get_rcu().
    3) All others must hold RTNL and use __in_dev_get_rtnl().
    
    There is one exception in net/ipv4/route.c which is in fact a pre-existing
    race condition.  I've marked it as such so that we remember to fix it.
    
    This patch is based on suggestions and prior work by Suzanne Wood and
    Paul McKenney.
