argument descriptor的意思|示意

Note that the command used takes as an argument the altered disk descriptor files from the mmcrnsd command above.

注意所使用的命令使用上面的 mmcrnsd 命令中的不同磁盘描述符文件作为参数。

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struct file指针，可以通过iocb->ki_flip获取。
