struct rcu_data *rdp
1376  rcu_lockdep_assert_cblist_protected(rdp)
1377  如果非Return the state portion of a sequence number previously returned* by rcu_seq_snap() or rcu_seq_current().或非raw_spin_trylock_rcu_node(rnp)则返回
1380  WARN_ON_ONCE(Move any callbacks whose grace period has completed to the* RCU_DONE_TAIL sublist, then compact the remaining sublists and* assign ->gp_seq numbers to any callbacks in the RCU_NEXT_TAIL* sublist. This function is idempotent, so it does not hurt to)
