Before we see how this mechanism is implemented in the Linux kernel, we must know actually what is it and how the Linux kernel uses it. Definitions like these represent a [callback](https://en.wikipedia.org/wiki/Callback_%28computer_programming%29) function which will be called either during initialization of the Linux kernel or right after it. Actually the main point of the `initcall` mechanism is to determine correct order of the built-in modules and subsystems initialization.
