.. certain details have been swept under the rug—chiefly that Torvalds' only significant vibe-coded contribution to the kernel thusfar was a ten-patch modification to page-caching that was promptly rescinded when other maintainers pointed out a race condition hidden in Claude Code's verbose output. [thenewstack.io] Torvalds ultimately dumped the mess onto human coder Kiryl Shutsemau's lap.
Perish the thought that the lead kernel maintainer would collaborate with other developers

“Linus Torvalds used Claude Code to build a Linux page cache fix that hit 23x read throughput, but kernel reviewers found a race before anything merged.”
Amanda Caswell: “.. Linus Torvalds turned to Anthropic’s Claude Code to tackle a kernel performance problem that developers have struggled with for more than two years”
“Torvalds had spent 18 months running a broken version of his own fix for the page-cache reference-counting bottleneck, while other developers had encountered problems with their approaches.”
“Reviewers have since identified a race condition and raised concerns about memory reclamation.”
“Torvalds has handed further development to Kiryl Shutsemau, a Linux kernel developer who previously worked on the same bottleneck.”
