[PATCH] rcu: join rcu_ctrlblk and rcu_state
This patch moves rcu_state into the rcu_ctrlblk. I think there are no reasons why we should have 2 different variables to control rcu state. Every user of rcu_state has also "rcu_ctrlblk *rcp" in the parameter list. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: Paul E. McKenney <paulmck@us.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
