Building cert_store.o with W=1 reveals this bug:
CC arch/s390/kernel/cert_store.o
arch/s390/kernel/cert_store.c:443:45: warning: ‘sprintf’ may write a terminating nul past the end of the destination [-Wformat-overflow=]
443 | sprintf(desc + name_len, ":%04u:%08u", vce->vce_hdr.vc_index, cs_token);
| ^
arch/s390/kernel/cert_store.c:443:9: note: ‘sprintf’ output between 15 and 18 bytes into a destination of size 15
443 | sprintf(desc + name_len, ":%04u:%08u", vce->vce_hdr.vc_index, cs_token);
Fix this by using the correct maximum width for each integer component
in both buffer length calculation and format string. Also switch to
using snprintf() to guard against potential future changes to the
integer range of each component.
Fixes:

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.
