I am still looking through the series, though, maybe I'll change my opinion. ;) > == allmodconfig FULL build == Did you try Clang CONFIG_LTO=y builds? > == LLM usage == > [...] > I extensively audited and rewrote a lot of it, and heavily edited commit > messages, the cover letter and comments. I feel like the commit logs still need a lot of work. The LLM verbosity problem appears in many of them, for example spending 80% of the commit log describing every step of some process as background before getting to the actual change. I think a human writing this would be much more terse about the background. I have, however, been known to be too terse in my own commit logs. :P > [...] > Nothing too controversial was included.

One area I think might solved via an LLM is the 3-pass kallsyms stuff. If we could get a deterministic kallsyms build in 1 pass, that would be very nice. A lot of people have tried, but it has eluded upstreaming. -Kees -- Kees Cook
