-    /// [packed]: https://doc.rust-lang.org/reference/type-layout.html#the-alignment-modifiers
-    ///
-    /// ### Example
-    ///
-    /// ```rust,compile_fail
-    /// #[repr(packed)]
-    /// pub struct Foo {
-    ///     field1: u64,
-    ///     field2: u8,
-    /// }
-    ///
-    /// fn main() {
-    ///     unsafe {
-    ///         let foo = Foo { field1: 0, field2: 0 };
-    ///         let _ = &foo.field1;
-    ///         println!("{}", foo.field1); // An implicit `&` is added here, triggering the lint.
-    ///     }
-    /// }
-    /// ```
-    ///
-    /// {{produces}}
-    ///
-    /// ### Explanation
-    ///
-    /// Creating a reference to an insufficiently aligned packed field is [undefined behavior] and
-    /// should be disallowed. Using an `unsafe` block does not change anything about this. Instead,
-    /// the code should do a copy of the data in the packed field or use raw pointers and unaligned
-    /// accesses. See [issue #82523] for more information.
-    ///
-    /// [undefined behavior]: https://doc.rust-lang.org/reference/behavior-considered-undefined.html
