strncpy() is deprecated for NUL-terminated destination buffers; use strscpy() instead. Since kzalloc() already zeroes out the destination buffer, the potential NUL-padding by strncpy() is unnecessary. strscpy() copies only the required characters and guarantees NUL-termination. Since the destination buffer has a fixed length, strscpy() automatically determines its size using sizeof() when the argument is omitted. This makes an explicit sizeof() call unnecessary. The source string is also NUL-terminated and meets the __must_be_cstr() requirement of strscpy(). No functional changes intended.

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.
