The comment near rcu_access_pointer() explicitly says: * Return the value of the specified RCU-protected pointer, but omit the * smp_read_barrier_depends() and keep the ACCESS_ONCE(). This is useful * when the value of this pointer is accessed, but the pointer is not * dereferenced, Yet you dereference the pointer... smells like fail to me. _______________________________________________ Virtualization mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/virtualization
