Squashfs copied the passed string (name) into a temporary buffer to ensure it was NUL-terminated. This however is completely unnecessary as the string is already NUL-terminated. So remove the deprecated strncpy() by completely removing the string copy. The background behind this unnecessary string copy is that it dates back to the days when Squashfs was an out of kernel patch. The code deliberately did not assume the string was NUL-terminated in case in future this changed (due to kernel changes). This would mean the out of tree patches would be broken but still compile OK.

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.
