The check_*_overflow() helpers will return results with potentially wrapped-around values. These values have always been checked by the selftests, so avoid the confusing language in the kern-doc. The idea of "safe for use" was relative to the expectation of whether or not the caller wants a wrapped value -- the calculation itself will always follow arithmetic wrapping rules.

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.
