During a W=1 build GCC 13.2 says:
net/core/selftests.c: In function ‘net_selftest_get_strings’:
net/core/selftests.c:404:52: error: ‘%s’ directive output may be truncated writing up to 279 bytes into a region of size 28 [-Werror=format-truncation=]
404 | snprintf(p, ETH_GSTRING_LEN, "%2d. %s", i + 1,
| ^~
net/core/selftests.c:404:17: note: ‘snprintf’ output between 5 and 284 bytes into a destination of size 32
404 | snprintf(p, ETH_GSTRING_LEN, "%2d. %s", i + 1,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
405 | net_selftests[i].name);

avoid it by using ethtool_sprintf().

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.
