Fail the test if it attempts to read a stat that doesn't exist, e.g. due
to a typo (hooray, strings), or because the test tried to get a stat for
the wrong scope. As is, there's no indiciation of failure and @data is
left untouched, e.g. holds '0' or random stack data in most cases.

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.
