`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We've already calculated bounds, possible truncation with '\0' or '\n' and manually NUL-terminated. The situation is now just a literal byte copy from one buffer to another, let's treat it as such and use a less ambiguous interface in memcpy.

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.
