This patch implements the initial Kunit based set of unit tests for HFS string operations. It checks functionality of hfs_strcmp(), hfs_hash_dentry(), and hfs_compare_dentry() methods. ./tools/testing/kunit/kunit.py run --kunitconfig ./fs/hfs/.kunitconfig [16:04:50] Configuring KUnit Kernel ...

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.
