I'm increasingly thinking that the Mesa policy of requiring commit
messages to be manually written (possibly with machine translation)
could be applied to the kernel.
I've heard multiple people saying how using LLMs made them more
productive, with an extreme example during the maintainer summit of
Linus talking about doing in a couple of months what would have likely
taken multiple years. The same people like to tell how they're in charge
of the whole process, how they control the machine, and how they have a
deep understanding of what they're doing. If that's the case, surely
writing a commit message will not increase the development time back
from a few months to a few years, the extra effort would be negligible.
Most commit messages generated by LLMs are quite easy to identify today.
Requiring a human-written message would be a good way to quickly ignore
patches submitted by meat proxies. And before anyone tells me this will
change very soon with <insert employer's new model>, I'll say we will
update our process when that happens.
