How Linux Kernel Selftests Prevent Broken Deployments

We explore the often-overlooked world of Linux kernel selftests, specifically focusing on how tools like Kselftest and LTP prevent regressions in modern server stacks. With the September 2026 release cycle bringing significant changes to memory management and networking subsystems, understanding these automated checks is crucial for sysadmins and developers who rely on stability over bleeding-edge features. We break down a specific case where a subtle change in page reclaim logic was caught by a selftest before it hit production, saving what could have been a catastrophic outage. This isn't about writing kernel code; it's about understanding the safety net that keeps your infrastructure running when you update the core operating system. #LinuxKernel #Selftests #Kselftest #LTP #SystemAdministration #DevOps #OpenSource #TechInfrastructure #ServerStability #SoftwareQuality #FexingoBusiness #BusinessPodcast #TechNews #LinuxDistros #EnterpriseTech #CloudComputing #EngineeringCulture #RiskManagement Keep every episode free: buymeacoffee.com/fexingo
