The Linux kernel is a large C codebase composed of many different subsystems. Each subsystem has its own purpose and operates independently. However, there are cases where one subsystem needs to be aware of information from other subsystems. The Linux kernel has a special mechanism to address this issue. This mechanism is called the notification … Read more
What is it exactly? Linux-Insides is actually an open-source ‘kernel encyclopedia’ repository that contains a series of chapter-style notes specifically analyzing how the Linux kernel operates. Imagine opening an electronic book titled ‘Inside the Linux Kernel,’ where each chapter includes handwritten experimental code, thought analyses, and debugging techniques by the author. Its goal is simple: … Read more
