Linux Kernel Memory Management

Behind every running application, service, or container in Linux, there's a powerful memory management system ensuring that resources are allocated efficiently, processes are isolated securely, and performance is optimized. In this course, we take you deep into the world of Linux Kernel Memory Management, exploring how the operating system handles memory under the hood—from basic paging to advanced allocation strategies.

This course is designed to demystify one of the most complex and critical areas of Linux internals. You'll begin by understanding how physical and virtual memory are structured in Linux. From there, we'll examine key kernel components such as memory zones, page tables, slab and slub allocators, the buddy system, and how the kernel efficiently maps, allocates, and tracks memory using structures like vm_area_struct and struct page.

You'll get hands-on with real-world tools like /proc, vmstat, top, and kmemleak, and you’ll learn to analyze memory-related issues, monitor usage, and debug potential problems. We also cover how system calls interact with memory and how memory is shared, protected, and reclaimed.

Whether you're an aspiring kernel developer, systems programmer, or someone who simply wants to go beyond the surface of Linux, this course will give you the skills and insights to truly master memory at the kernel level.
