The Sashiko patch-review system

Roman Gushchin has announced theexistence of an LLM-driven patch-review system named Sashiko. It automatically creates reviewsfor all patches sent to the linux-kernel mailing list (and some others).

In my measurement, Sashiko was able to find 53% of bugs based on acompletely unfiltered set of 1,000 recent upstream issues using"Fixes:" tags (using Gemini 3.1 Pro). Some might say that 53% isnot that impressive, but 100% of these issues were missed by humanreviewers.

Sashiko is built on Chris Mason's review prompts (covered here in October 2025), but theimplementation has evolved considerably.
