According to Paul it is fine to use RCU primitives (when accompanied with proper comments) when the read-size critical section is guarded by spin_lock_irqsave()/spin_lock_irqsrestore() instead of rcu_read_lock()/rcu_read_unlock() and writers synchronize with synchronize_sched(), not synchronize_rcu(). Your patch will trigger warnign on such valid usages. -- Dmitry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
