I am not sure if this is a bug of rcu lockdep, because I am testing my patch when this occurred. However, in the backtrace, there is none of the functions that I touched, weird. So, please help to check if this is a bug of rcu lockdep. Please Cc netdev when necessary. Thanks much! --00163630eda98b67a50481838ef4 Content-Type: text/plain; charset=US-ASCII; name="rcu-lockdep-bug.txt" Content-Disposition: attachment; filename="rcu-lockdep-bug.txt"
