Please don't cry if my Python code looks like C. I'm just a kernel developer.

+N.B. If `CONFIG_GCC_PLUGIN*` options are automatically disabled during your kernel compilation,
+that means that your gcc doesn't support plugins. For example, if you have `gcc-7` on Ubuntu,
+try to install `gcc-7-plugin-dev` package, it should help.
