From: Danilo Krummrich <dakr@kernel.org>

commit c8cfa8d0c0b10be216861fe904ea68978b1dcc97 upstream.

`Box` provides the simplest way to allocate memory for a generic type
with one of the kernel's allocators, e.g. `Kmalloc`, `Vmalloc` or
`KVmalloc`.

In contrast to Rust's `Box` type, the kernel `Box` type considers the
kernel's GFP flags for all appropriate functions, always reports
allocation failures through `Result<_, AllocError>` and remains
independent from unstable features.

+/// The kernel's [`Box`] type -- a heap allocation for a single value of type `T`.
+///
+/// This is the kernel's version of the Rust stdlib's `Box`. There are several differences,
+/// for example no `noalias` attribute is emitted and partially moving out of a `Box` is not
+/// supported. There are also several API differences, e.g. `Box` always requires an [`Allocator`]
+/// implementation to be passed as generic, page [`Flags`] when allocating memory and all functions
+/// that may allocate memory are fallible.
+///
+/// `Box` works with any of the kernel's allocators, e.g. [`Kmalloc`], [`Vmalloc`] or [`KVmalloc`].
+/// There are aliases for `Box` with these allocators ([`KBox`], [`VBox`], [`KVBox`]).
+///
+/// When dropping a [`Box`], the value is also dropped and the heap memory is automatically freed.
+///
+/// # Examples
+///
+/// ```
+/// let b = KBox::<u64>::new(24_u64, GFP_KERNEL)?;
+///
+/// assert_eq!(*b, 24_u64);
