David Vernet says: ==================== In [0], we added support for storing struct task_struct * objects as kptrs. This patch set extends this effort to also include storing struct cgroup * object as kptrs. As with tasks, there are many possible use cases for storing cgroups in maps. During tracing, for example, it could be useful to query cgroup statistics such as PSI averages, or tracking which tasks are migrating to and from the cgroup.

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 Restructured Text 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.
