ReCite flagged 869 stale comments, Linux accepted 50 patches

ReCite scanned Linux kernel v6.18-rc1 and found 869 code comments describing functions that no longer match the code, per the paper introducing it. Comments like these send engineers chasing behavior the code doesn't have anymore. In a codebase the size of the kernel, that's hundreds of small traps for anyone reading the comment instead of the code.

Researchers generated repair suggestions for those stale references and manually checked 200 of the sampled fixes. They rated 178 useful. Of those, 85 applied directly with no further editing, leaving 93 that needed some cleanup first.

The tool traces each unresolved function reference through the project's Git history. It grounds every repair in how that function actually changed over time, instead of guessing from the current code alone.

ReCite also got fixes merged: Linux maintainers accepted 50 of the 75 patches it generated for the kernel. The paper doesn't say why the other 25 patches were turned down.
