The best on the subject since LDD3
Format: Paperback
I found this book as impacting me as LDD (by Rubini etc) has been in its days, a de-facto standard established to the point that people keep searching for LDD4/LDD5 to these days, that much desirable.
Since LDD3 the last update on 2.6, this book (as well as kernel debugging and hands-on systems programming) is a valuable source of information for modern kernels 5 and 6 for a few years to come.
Knowledgeable and easy to follow, captivating attention to keep on reading it through, impressive for a technical book. LDD4+ has now found reincarnated, thank you very much for all the effort composing it!

Compelling, informative, and accurate
Format: Kindle
I really could not be happier with the pace and level of detail this book provides. I am a very surface-level Linux user and I wanted to dive in head first. I often find that when I learn about something that I consider really hard or intimidating in tech, I get better at day-to-day use of the tools and my confidence grows. This book is a real confidence-booster if you crave the knowledge of how things work under the hood.

A Hands-On and Deep Guide to Linux Kernel Programming
Format: Paperback
Linux Kernel Programming, Second Edition is a very practical and well-structured book for anyone who wants to understand how the Linux kernel works. It focuses on both theory and real hands-on learning. The book uses a clear style and explains complex topics in a simple way. It is designed to help readers build real skills, not just read concepts. It is especially useful for developers who want to work closer to the operating system.
One of the most interesting parts of the book is the strong introduction to kernel programming. It explains how to set up a development environment, build the Linux kernel from source, and write the first kernel module. This section gives readers a solid starting point and builds confidence early in the learning process. It also explains why loadable kernel modules are widely used in real-world projects.
Another highlight is the deep coverage of kernel internals. The book explains core concepts such as kernel architecture, processes, threads, and the difference between user mode and kernel mode. These ideas are often hard to understand, but the book presents them in a clear and structured way. This helps readers see how the operating system really works under the surface.
The memory management section is especially strong and detailed. The book spends several chapters explaining how memory is allocated and managed inside the kernel. It also explains advanced topics such as page allocation, memory reclaim, and the out-of-memory system. These chapters are very useful for understanding performance and stability in real systems.
Another very interesting section is the coverage of CPU scheduling. The book explains how the Linux kernel decides which task runs at a given time. It introduces scheduling policies, priorities, and modern features like control groups. The explanations are practical and supported by examples, which makes the topic easier to follow.
The chapters on kernel synchronization are also a major highlight. They explain concepts such as locks, atomic operations, and deadlock prevention. These topics are critical for writing safe and reliable kernel code. The book also shows real examples and common mistakes, which helps readers avoid problems in their own work.
Another strength of the book is its hands-on approach. It includes many kernel modules, scripts, and examples that readers can try themselves. This makes learning more engaging and helps turn theory into real skills. The focus on practical work makes the book stand out from more theoretical resources.
Overall, this book is a great choice for developers, system programmers, and engineers who want to understand the Linux kernel in depth. It starts with the basics and moves into advanced topics in a smooth way. The combination of clear explanations and practical examples makes it a strong and valuable learning resource.

Poor quality binding
Format: Paperback, Format: Paperback
Binding glue fell apart in less than a week and the pages fell out. Content is great though and I have a shiny new kernel based on Kali. 4 stars despite the binding because the content is top tier if you love all things Linux 🤌
