The ->gp_seq field is the counterpart of the field of the same +name in the rcu_state and rcu_node structures. The +->gp_seq_needed field is the counterpart of the field of the same +name in the rcu_node structure. They may each lag up to one behind their rcu_node counterparts, but in CONFIG_NO_HZ_IDLE and CONFIG_NO_HZ_FULL kernels can lag -- 2.7.4
