Linux 5.17 Making It Easier To Build A Kernel With All The Shiny Debug Features

Over the years the Linux kernel has picked up many different sanitizers, memory leak detectors, and other features for helping to diagnose and address deficiencies in the kernel. However, all of these debugging-optimized features aren't centrally located that can make it difficult for system administrators and developers to spot these numerous features when configuring a kernel build manually. Now with Linux 5.17 that is changing.

Fast Kernel Headers v2 Posted - Speeds Up Clang-Built Linux Kernel Build By ~88%

What may end up being one of the greatest Linux kernel features of 2022 is the recently published "Fast Kernel Headers" effort for cleaning up the kernel headers and dramatically speeding up Linux kernel builds both for absolute/clean and incremental builds. Fast Kernel Headers can cut the Linux kernel build time in half or greater and out this weekend are the v2 patches.

Massive ~2.3k Patch Series Would Improve Linux Build Times 50~80% & Fix "Dependency Hell"

Longtime Linux kernel developer Ingo Molnar posted a massive set of patches today: 2,297 patches that have been in the works since late 2020 and completely rework the Linux kernel's header file hierarchy. The goal of this "fast kernel headers" effort is to speed up kernel build times and also clean-up a lot of things in the process to address the "dependency hell".
