Name: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.
Proto:static inline int __ptr_ring_produce(struct ptr_ring *r, void *ptr)
Type:int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct ptr_ring * | r | |
| void * | ptr |
| 105 | If Value for the false possibility is greater at compile time(! Read-only by both the producer and the consumer ) || queue[producer] Then Return -ENOSPC |
| 110 | smp_wmb() |
| 112 | WRITE_ONCE(queue[producer++], ptr) |
| 113 | If Value for the false possibility is greater at compile time(producer >= Read-only by both the producer and the consumer ) Then producer = 0 |
| 115 | Return 0 |
