When building with 'make W=1', clang warns about a mismatched
format string:
net/ipv6/ah6.c:710:4: error: format specifies type 'unsigned short' but the argument has type 'int' [-Werror,-Wformat]
aalg_desc->uinfo.auth.icv_fullbits/8);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
include/linux/printk.h:375:34: note: expanded from macro 'pr_info'
printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__)
~~~ ^~~~~~~~~~~
net/ipv6/esp6.c:1153:5: error: format specifies type 'unsigned short' but the argument has type 'int' [-Werror,-Wformat]
aalg_desc->uinfo.auth.icv_fullbits / 8);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
include/linux/printk.h:375:34: note: expanded from macro 'pr_info'
printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__)
~~~ ^~~~~~~~~~~
Here, the result of dividing a 16-bit number by a 32-bit number
produces a 32-bit result, which is printed as a 16-bit integer.
Change the %hu format to the normal %u, which has the same effect
but avoids the warning.

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.
