Here, iocb is, of course, the iocb you were given when the request was initiated.

当然，这里的iocb就是发起请求时的iocb。

Once you have called aio_complete(), you no longer own the IOCB or the user buffer, and should not touch them again.

一旦调用aio_complete()，驱动程序就不再拥有IOCB或者用户缓冲区了，不应该再触碰它们。

The iocb argument can usually be treated as an opaque cookie used by the AIO subsystem; if you need the struct file pointer for this file descriptor, however, you can find it as iocb->ki_filp.

通常可以把iocb看作AIO子系统使用的不透明数据结构。然而，如果需要文件描述符的structfile指针，可以通过iocb->ki_flip获取。
