Linux kernel modifications for the Kernel Hacking exam

Currently the registering of function graph is to pass in a entry and return function. We need to have a way to associate those functions together where the entry can determine to run the return hook. Having a structure that contains both functions will facilitate the process of converting the code to be able to do such. This is similar to the way function hooks are enabled (it passes in ftrace_ops). Instead of passing in the functions to use, a single structure is passed in to the registering function. The unregister function is now passed in the fgraph_ops handle. When we allow more than one callback to the function graph hooks, this will let the system know which one to remove.

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.
