Linus Torvalds's first LLM-assisted patch series

Linus Torvalds has released his first LLM-assisted patch series, which he discussed at the recent Maintainers Summit. This series, consisting of ten patches, aims to enhance folio lookup performance. It achieves this by identifying "hot" folios and delaying their release until after an RCU period. This allows both folio lookup and data access to occur within an RCU-protected region, eliminating the need for refcount taking in the fastpath when user copies don't cause page faults.
