__ptr_ring_produce

函数名称：Note: callers invoking this in a loop must use a compiler barrier,* for example cpu_relax(). Callers must hold producer_lock.* Callers are responsible for making sure pointer that is being queued* points to a valid data.

函数原型：static inline int __ptr_ring_produce(struct ptr_ring *r, void *ptr)

返回类型：int

参数：

类型	参数	名称
struct ptr_ring *	r
void *	ptr

如果此条件成立可能性小(为编译器优化)(! Read-only by both the producer and the consumer )或queue[producer]则返回:负ENOSPC

110

smp_wmb()

112

WRITE_ONCE(queue[producer++], ptr)

113

如果此条件成立可能性小(为编译器优化)(producer >= Read-only by both the producer and the consumer )则producer等于0

115

返回:0
