According to Documentation/core-api/printk-formats.rst, size_t should be
printed with %zu, rather than %Zu.
In addition, using %Zu triggers a warning on clang (-Wformat-extra-args):
net/sctp/chunk.c:196:25: warning: data argument not used by format string [-Wformat-extra-args]
__func__, asoc, max_data);

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.
