 The tracking issue for this feature is: [#85512](https://github.com/rust-lang/rust/issues/85512).
 
 ------------------------
 
-This feature allows you to cause any lint to produce a warning even if the lint has a different level by default or another level is set somewhere else. For instance, the `force-warns` option can be used to make a lint (e.g., `dead_code`) produce a warning even if that lint is allowed in code with `#![allow(dead_code)]`.
