Besides the `rootfs_initcall` level, there are additional `console_initcall`, `security_initcall` and other secondary `initcall` levels. The last thing that we have missed is the set of the `*_initcall_sync` levels. Almost each `*_initcall` macro that we have seen in this part, has macro companion with the `_sync` prefix:

In this part we saw the important mechanism of the Linux kernel which allows to call a function which depends on the current state of the Linux kernel during its initialization.
在这部分中，我们看到了Linux内核的一项重要机制，即在初始化期间允许调用依赖于Linux内核当前状态的函数。In this part we saw the important mechanism of the Linux kernel which allows to call a function which depends on the current state of the Linux kernel during its initialization.
