Linus Torvalds hands Claude Code a rewrite of the Linux page-cache read path

On 11 October 2026, Linus Torvalds published a kernel branch that reads from the page cache without taking folio references, written with the Claude Code coding assistant to relieve contention between many threads reading one file. If you run a heavily concurrent file server, watch this patch series: it targets the exact multi-threaded small-read bottleneck you feel, and it may land in Linux 7.4.
