Hi, I'm currently reading the memory management source code and get stuck on a function. In arch/x86/mm/init.c, there is a function called split_mem_range[0]. Its logic is very complicated and I can't figure out what it does. I have added some debug statements in this function to print all variable, but I still can't understand it. I have also searched it on Google and couldn't find any helpful articles. Could someone give me some help about what on earth this function does? Many thanks!
