Thanks. I just replaced
#ifdef CONFIG_PREEMPTION #define rcu_read_lock() preempt_disable() #define rcu_read_unlock() preempt_enable() #else #define rcu_read_lock() do {} while(0) #define rcu_read_unlock() do {} while(0) #endif
with
#define rcu_read_lock() preempt_disable() #define rcu_read_unlock() preempt_enable()
because preempt_disable() is a no-op on CONFIG_PREEMPT=n anyway. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
