Sergio González Collado b8abcba6e4 Kunit to check the longest symbol length 
commit c104c16073 upstream.

The longest length of a symbol (KSYM_NAME_LEN) was increased to 512
in the reference [1]. This patch adds kunit test suite to check the longest
symbol length. These tests verify that the longest symbol length defined
is supported.

This test can also help other efforts for longer symbol length,
like [2].

The test suite defines one symbol with the longest possible length.

The first test verify that functions with names of the created
symbol, can be called or not.

The second test, verify that the symbols are created (or
not) in the kernel symbol table.

README 

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.
