Subject: [PATCH tip/core/rcu 04/22] rcu: Prevent excessive line length in RCU_STATE_INITIALIZER()

From: "Paul E. McKenney" <paul.mckenney@...aro.org>

Upcoming rcu_barrier() concurrency commits will result in line lengths
greater than 80 characters in the RCU_STATE_INITIALIZER(), so this commit
shortens the name of the macro's argument to prevent this.
