McKenney" <paulmck@...ux.vnet.ibm.com> Subject: [PATCH tip/core/rcu 15/15] rcu: Remove exports from rcu_idle_exit() and rcu_idle_enter() The rcu_idle_exit() and rcu_idle_enter() functions are exported because they were originally used by RCU_NONIDLE(), which was intended to be usable from modules. However, RCU_NONIDLE() now instead uses rcu_irq_enter_irqson() and rcu_irq_exit_irqson(), which are not exported, and there have been no complaints. This commit therefore removes the exports from rcu_idle_exit() and rcu_idle_enter(). Reported-by: Peter Zijlstra <peterz@...radead.org> Signed-off-by: Paul E.
