commitcdb5052534upstream. Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. Here are some helpers that will be used to mark subtests as skipped if a feature is not supported. Marking as a fix for the commit introducing this selftest to help with the backports. While at it, also check if kallsyms feature is available as it will also be used in the following commits to check if MPTCP features are available before starting a test.

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.
