Eric Dumazet 2ca4f6ca45 rxrpc: use rcu protection while reading sk->sk_user_data ... We need to extend the rcu_read_lock() section in rxrpc_error_report() and use rcu_dereference_sk_user_data() instead of plain access to sk->sk_user_data to make sure all rules are respected. The compiler wont reload sk->sk_user_data at will, and RCU rules prevent memory beeing freed too soon.
