That example was added in 2008. In 2015, we restricted access to the PFNs in the pagemap to CAP_SYS_ADMIN, making that approach quite less usable. It's 2024 now, and using that racy and low-lewel mechanism to calculate the USS should not be considered a good example anymore. /proc/$pid/smaps and /proc/$pid/smaps_rollup can do a much better job without any of that low-level handling. Let's just drop that example.

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.
