GoKawiilLinus Torvalds submits first LLM-assisted kernel patch series
Torvalds posted a ten-patch series that improves folio lookup by marking 'hot' folios for delayed release under an RCU grace period, allowing both the lookup and the actual data access to happen within an RCU-protected region without taking a refcount on the fast path. The change reportedly yields an order-of-magnitude speedup on a read()-heavy benchmark, though reviewers have already found a race condition requiring further fixes.
