The function_graph boot up self test emulates the tr->init() function in order to add a wrapper around the function graph tracer entry code to test for lock ups and such. But it does not emulate the tr->reset(), and just calls the function_graph tracer tr->reset() function which will use its own fgraph_ops to unregister function tracing with. As the fgraph_ops is becoming more meaningful with the register_ftrace_graph() and unregister_ftrace_graph() functions, the two need to be the same. The emulated tr->init() uses its own fgraph_ops descriptor, which means the unregister_ftrace_graph() must use the same ftrace_ops, which the selftest currently does not do. By emulating the tr->reset() as the selftest does with the tr->init() it will be able to pass the same fgraph_ops descriptor to the unregister_ftrace_graph() as it did with the register_ftrace_graph().

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.
