I assume that you have gone through Chapter 1, Kernel Workspace Setup, and have appropriately prepared a guest VM running Ubuntu 18.04 LTS (or a later stable release) and installed all the required packages. If not, I recommend you do this first. To get the most out of this book, I strongly recommend you first set up the workspace environment, including cloning this book's GitHub repository for the code (https://github.com/PacktPublishing/Linux-Kernel-Programming), and work on it in a hands-on fashion.
I assume that you are familiar with basic virtual memory concepts, the user-mode process Virtual Address Space (VAS) layout of segments, user-and kernel-mode stacks, the task structure, and so on. If you're unsure on this footing, I strongly suggest you read the preceding chapter first.
