As opposed to the --diff option, --commit can get ref names instead of commit hashes. When using the --commit option, the script resets the working directory to the commit before the given ref, by adding '~' to the end of the ref. However, the 'HEAD' ref is relative, and so when the working directory is reset to 'HEAD~', 'HEAD' points to what was 'HEAD~'. Then when the script resets to 'HEAD' it actually stays in the same commit. In this case, the script won't report any cases because there is no diff between the cases of the two refs. Prevent the user from using HEAD refs. A better solution might be to resolve the refs before doing the reset, but for now just disallow such refs.

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.
