If a queue is plugged, the I/O scheduler * is still adding and merging requests on the queue. Once the queue * gets unplugged, the request_fn defined for the queue is invoked and * transfers started. **/ void generic_unplug_device(struct request_queue *q) { spin_lock_irq(q->queue_lock); - --[[linux-2.6.25/spin_lock_irq()]] __generic_unplug_device(q); - --[[linux-2.6.25/__generic_unplug_device()]] spin_unlock_irq(q->queue_lock); - --[[linux-2.6.25/spin_unlock_irq()]] } EXPORT_SYMBOL(generic_unplug_device); -関数をエクスポートする。 --[[linux-2.6.25/EXPORT_SYMBOL()]] *コメント [#f1973072] #comment
