How Linus Torvalds Pulled Off the Impossible Linux Merge ...

What this episode covers

In this episode of Open Source with Fexingo, Lucas and Luna dive into the story of the most controversial merge in Linux kernel history: the 2004 'big kernel lock' removal and the threading rewrite that nearly broke everything. They walk through how Linus Torvalds and a small team of maintainers managed to refactor one of the most critical subsystems in the world's most-used operating system without breaking userland — and what that teaches us about governance, trust, and technical debt in open source. Along the way, they touch on the cultural norms that made the merge possible, the role of the Linux Foundation, and why the kernel community's approach to breaking changes is radically different from corporate software. A conversation about why some open source projects survive their own complexity. #Linux #LinusTorvalds #OpenSource #KernelDevelopment #BigKernelLock #Threading #TechnicalDebt #SoftwareEngineering #CommunityGovernance #LinuxFoundation #Git #MergeConflict #FexingoBusiness #BusinessPodcast #Technology #Conversation #Podcast #OpenSourceWithFexingo Keep every episode free: buymeacoffee.com/fexingo
