This check has a signedness bug and does not work. If "length" is larger than "PAGE_SIZE" then "PAGE_SIZE - length" is not negative but instead it is a large unsigned value. Fortunately, Takashi Iwai changed this code to use scnprint() instead of snprintf() so now "length" is never larger than "PAGE_SIZE - 1" and the check can be removed.

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.
