`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. `dax_id->dev_name` is expected to be NUL-terminated and has been zero-allocated. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer. Moreover, due to `dax_id` being zero-allocated the padding behavior of `strncpy` is not needed and a simple 1:1 replacement of strncpy -> strscpy should suffice.

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.
