Anton Ivanov 612a8c8e0b um: vector: Replace locks guarding queue depth with atomics ... UML vector drivers use ring buffer structures which map preallocated skbs onto mmsg vectors for use with sendmmsg and recvmmsg. They are designed around a single consumer, single producer pattern allowing simultaneous enqueue and dequeue. Lock debugging with preemption showed possible races when locking the queue depth. This patch addresses this by removing extra locks, adding barriers and making queue depth inc/dec and access atomic.
