When CONFIG_DYNAMIC_FTRACE is not set, the function fgraph_update_pid_func() doesn't do anything. Currently, most of its logic is within a "#ifdef CONFIG_DYNAMIC_FTRACE" block, but its variables were declared outside that, and when DYNAMIC_FTRACE is not set, it produces unused variable warnings. Instead, just place it (and the helper function fgraph_pid_func()) within the #ifdef block and have the header file use a empty stub function for when DYNAMIC_FTRACE is not defined.

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.
