For pinned and unpinned initialization of structs, a trait named `InPlaceInit` exists for uniform access. `Arc` did not implement `InPlaceInit` yet, although the functions already existed. The main reason for that, was that the trait itself returned a `Pin<Self>`. The `Arc` implementation of the kernel is already implicitly pinned. To enable `Arc` to implement `InPlaceInit` and to have uniform access, for in-place and pinned in-place initialization, an associated type is introduced for `InPlaceInit`. The new implementation of `InPlaceInit` for `Arc` sets `Arc` as the associated type. Older implementations use an explicit `Pin<T>` as the associated type. The implemented methods for `Arc` are mostly moved from a direct implementation on `Arc`. There should be no user impact. The implementation for `ListArc` is omitted, because it is not merged yet.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
