Linux kernel source tree

`strncpy` is deprecated and as such we should prefer more robust and
less ambiguous interfaces.
In this case, all of `press_str`, `repeat_str` and `release_str` are
explicitly marked as nonstring:
| struct { /* valid when type == INPUT_TYPE_KBD */
| char press_str[sizeof(void *) + sizeof(int)] __nonstring;
| char repeat_str[sizeof(void *) + sizeof(int)] __nonstring;
| char release_str[sizeof(void *) + sizeof(int)] __nonstring;
| } kbd;
... which makes `strtomem_pad` a suitable replacement as it is
functionally the same whilst being more obvious about its behavior.

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.
