Support linked lists that can hold many different structs at once. This is generally done using trait objects. The main challenge is figuring what the struct is given only a pointer to the ListLinks. We do this by storing a pointer to the struct next to the ListLinks field. The container_of operation will then just read that pointer. When the type is a trait object, that pointer will be a fat pointer whose metadata is a vtable that tells you what kind of struct it is. Heterogeneous lists are heavily used by Rust Binder. There are a lot of so-called todo lists containing various events that need to be delivered to userspace next time userspace calls into the driver. And there are quite a few different todo item types: incoming transaction, changes to refcounts, death notifications, and more.

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.
