An LLM-assisted patch series speeds Linux kernel builds by 36 to 90 percent

Sources: primary, discussion
Summary: Lorenzo Stoakes reports an all-modules build about 36 percent faster, incremental builds up to 70 percent faster and noop builds up to about 90 percent faster. The patches parallelize stages that ran single-threaded in Kbuild, kallsyms, modpost, objtool, mksysmap and the Rust build system.
Why it matters: Build latency is the inner loop of kernel work, and the reported gains come from parallelizing existing serial stages rather than from new hardware.
Follow-up: Track which patches are accepted upstream and in which release.
