Format attributes on functions taking format string can help compilers
detect argument type or count mismatches.
Please the compiler when building with W=1:
security/tomoyo/audit.c: In function ‘tomoyo_init_log’:
security/tomoyo/audit.c:290:9: error: function ‘tomoyo_init_log’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]
290 | vsnprintf(buf + pos, len - pos, fmt, args);
| ^~~~~~~~~
security/tomoyo/audit.c: In function ‘tomoyo_write_log2’:
security/tomoyo/audit.c:376:9: error: function ‘tomoyo_write_log2’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]
376 | buf = tomoyo_init_log(r, len, fmt, args);
| ^~~
security/tomoyo/common.c: In function ‘tomoyo_addprintf’:
security/tomoyo/common.c:193:9: error: function ‘tomoyo_addprintf’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]
193 | vsnprintf(buffer + pos, len - pos - 1, fmt, args);

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.
