One way to explain what `ListArc` does is that it controls exclusive access to the prev/next pointer field in a refcounted object. The feature of having a special reference to a refcounted object with exclusive access to specific fields is useful for other things, so provide a general utility for that. This is used by Rust Binder to keep track of which processes have a reference to a given node. This involves an object for each process/node pair, that is referenced by both the process and the node. For some fields in this object, only the process's reference needs to access them (and it needs mutable access), so Binder uses a ListArc to give the process's reference exclusive access.

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.
