Add a test that checks that if pid namespaces are configured the fdinfo file of a pidfd contains an NSpid: entry containing the process id in the current and additionally all nested namespaces. In the case that a pidfd is from a pid namespace not in the same namespace hierarchy as the process accessing the fdinfo file, ensure the 'NSpid' shows 0 for that pidfd, analogous to the 'Pid' entry.

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.
