    gre: get rid of ipgre_lock · 1507850b
    Eric Dumazet authored Sep 15, 2010
    
    
    As RTNL is held while doing tunnels inserts and deletes, we can remove
    ipgre_lock spinlock. My initial RCU conversion was conservative and
    converted the rwlock to spinlock, with no RTNL requirement.
    
    Use appropriate rcu annotations and modern lockdep checks as well.
