-/// Used to specify the pinning information of the fields of a struct.
-///
-/// This is somewhat similar in purpose as
-/// [pin-project-lite](https://crates.io/crates/pin-project-lite).
-/// Place this macro on a struct definition and then `#[pin]` in front of the attributes of each
-/// field you want to structurally pin.
-///
-/// This macro enables the use of the [`pin_init!`] macro. When pin-initializing a `struct`,
-/// then `#[pin]` directs the type of initializer that is required.
-///
-/// If your `struct` implements `Drop`, then you need to add `PinnedDrop` as arguments to this
-/// macro, and change your `Drop` implementation to `PinnedDrop` annotated with
-/// `#[`[`macro@pinned_drop`]`]`, since dropping pinned values requires extra care.
-///
-/// # Examples
-///
-/// ```ignore
-/// # #![feature(lint_reasons)]
-/// # use kernel::prelude::*;
-/// # use std::{sync::Mutex, process::Command};
-/// # use kernel::macros::pin_data;
-/// #[pin_data]
-/// struct DriverData {
-///     #[pin]
