+use crate::bindings;
+
+/// Creates a [`SpinLock`] initialiser with the given name and a newly-created lock class.
+///
+/// It uses the name if one is given, otherwise it generates one based on the file name and line
+/// number.

+
+/// A spinlock.
+///
+/// Exposes the kernel's [`spinlock_t`]. When multiple CPUs attempt to lock the same spinlock, only
+/// one at a time is allowed to progress, the others will block (spinning) until the spinlock is
+/// unlocked, at which point another CPU will be allowed to make progress.
+///
+/// Instances of [`SpinLock`] need a lock class and to be pinned. The recommended way to create such
+/// instances is with the [`pin_init`](crate::pin_init) and [`new_spinlock`] macros.
+///
+/// # Examples
+///
+/// The following example shows how to declare, allocate and initialise a struct (`Example`) that
+/// contains an inner struct (`Inner`) that is protected by a spinlock.
+///
+/// ```
+/// use kernel::{init::InPlaceInit, init::PinInit, new_spinlock, pin_init, sync::SpinLock};
+///
+/// struct Inner {
+///     a: u32,
+///     b: u32,
+/// }
+///
+/// #[pin_data]
+/// struct Example {
+///     c: u32,
+///     #[pin]
+///     d: SpinLock<Inner>,
+/// }
+///
+/// impl Example {
+///     fn new() -> impl PinInit<Self> {
+///         pin_init!(Self {
+///             c: 10,
+///             d <- new_spinlock!(Inner { a: 20, b: 30 }),
+///         })
+///     }
+/// }
+///
+/// // Allocate a boxed `Example`.
+/// let e = Box::pin_init(Example::new())?;
+/// assert_eq!(e.c, 10);
+/// assert_eq!(e.d.lock().a, 20);
+/// assert_eq!(e.d.lock().b, 30);
+/// ```
+///
+/// The following example shows how to use interior mutability to modify the contents of a struct
+/// protected by a spinlock despite only having a shared reference:
+///
+/// ```
+/// use kernel::sync::SpinLock;
+///
+/// struct Example {
+///     a: u32,
+///     b: u32,
+/// }
+///
+/// fn example(m: &SpinLock<Example>) {
+///     let mut guard = m.lock();
+///     guard.a += 10;
+///     guard.b += 20;
+/// }
+/// ```
+///
+/// [`spinlock_t`]: ../../../../include/linux/spinlock.h
+pub type SpinLock<T> = super::Lock<T, SpinLockBackend>;
+
+/// A kernel `spinlock_t` lock backend.
