Subject: [PATCH] rcu: Remove rcu_*_state declaration
Date: Wed, 9 Jan 2019 22:13:28 +0800 [thread overview]
Message-ID: <1547043208-11941-1-git-send-email-peng.hao2@zte.com.cn> (raw)
Because of just only one set of rcu_state, the declaration of
rcu_sched_state/rcu_bh_state/rcu_preempt_state is unnecessary.
