Running the ftrace selftests on the latest kernel caused the kprobe_eventname test to fail. It was due to the test that searches for a function with at "dot" in the name and adding a probe to that. Unfortunately, for this test, it picked: optimize_nops.isra.2.cold.4 Which happens to be marked as "__init", which means it no longer exists in the kernel! (kallsyms keeps those function names around for tracing purposes) As only functions that still exist are in the available_filter_functions file, as they are removed when the functions are freed at boot or module exit, have the test search for a function with ".isra." in the name as well as being in the available_filter_functions (if the file exists).

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.
