Compiling with W=1 emitted the following warning (Compiler: gcc (x86-64, ver. 13.2.1, .config: result of make allyesconfig, "Treat warnings as errors" turned off): kernel/workqueue.c:2188:54: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size between 5 and 14 [-Wformat-truncation=] kernel/workqueue.c:2188:50: note: directive argument in the range [0, 2147483647] kernel/workqueue.c:2188:17: note: ‘snprintf’ output between 4 and 23 bytes into a destination of size 16 setting "id_buf" to size 23 will silence the warning, since GCC determines snprintf's output to be max. 23 bytes in line 2188.

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.
