[$] Questions for the Technical Advisory Board

The nature and role of the Linux Foundation's Technical Advisory Board (TAB) is not well-understood, though a recent LWN article shed some light on its role and history. At the 2025 Linux Plumbers Conference (LPC), the TAB held a question and answer session to address whatever it was the community wanted to know (video). Those questions ended up covering the role of large language models in kernel development, what it is like to be on the TAB, how the TAB can help grease the wheels of corporate bureaucracy, and more.

Release candidates are not feature drops โ€” they are checkpoints. And rc4 reflects exactly that role. What Does rc4 Mean in the Kernel Cycle? By the time the fourth release candidate arrives, the merge window is long closed. That means all major features for Linux 6.19 are already in place, and the focus has shifted entirely to: Fixing bugs introduced earlier in the cycle Addressing regressions reported by testers Refining drivers, subsystems, and architecture-specific code In other words, rc4 is about stability and correctness, not surprises. Whatโ€™s Changed in Linux 6.19-rc4 While rc releases donโ€™t usually headline major features, they do in
