There is times when tracing the tracing infrastructure can be useful for debugging the tracing code. Currently all files in the tracing directory are set to "notrace" the functions. Add a new config option FUNCTION_SELF_TRACING that will allow some of the files in the tracing infrastructure to be traced. It requires a config to enable because it will add noise to the function tracer if events and other tracing features are enabled. Tracing functions and events together is quite common, so not tracing the event code should be the default.

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.
