This one is just a minor nuisance for people going through /proc/swaps if any of their swapareas is bigger than, or equal to 1073741824 pages (4TB). seq_printf() format string casts as uint the conversion from pages to KB, and that will overflow in the aforementioned case. Albeit being almost unthinkable that someone would actually set up such big of a single swaparea, there is a ticket recently filed against RHEL: https://bugzilla.redhat.com/show_bug.cgi?id=2008812 Given that all other codesites that use format strings for the same swap pages-to-KB conversion do cast it as ulong, this patch just follows suit.

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.
