Overview of this book

Mastering Linux Kernel Development looks at the Linux kernel, its internal arrangement and design, and various core subsystems, helping you to gain significant understanding of this open source marvel. You will look at how the Linux kernel, which possesses a kind of collective intelligence thanks to its scores of contributors, remains so elegant owing to its great design. This book also looks at all the key kernel code, core data structures, functions, and macros, giving you a comprehensive foundation of the implementation details of the kernel’s core services and mechanisms. You will also look at the Linux kernel as well-designed software, which gives us insights into software design in general that are easily scalable yet fundamentally strong and safe. By the end of this book, you will have considerable understanding of and appreciation for the Linux kernel.

Memory allocators

Having looked at how physical memory is organized, and represented through core data structures, we will now shift our attention to management of physical memory for processing allocation and deallocation requests. Memory allocation requests can be raised by various entities in the system, such as usermode process, drivers, and filesystems. Depending on the type of entity and context from which allocation is being requested, allocations returned might need to meet certain characteristics, such as page-aligned physically contiguous large blocks or physically contiguous small blocks, hardware cache aligned memory, or physically fragmented blocks that are mapped to virtually contiguous address space.

To efficiently manage physical memory, and cater to memory as per chosen priority and pattern, the kernel engages with a group of memory allocators. Each allocator...
