The types in calculation of the used percentage in the reclaiming
messages are both u64, though bg->length is either 1GiB (non-zoned) or
the zone size in the zoned mode. The upper limit on zone size is 8GiB so
this could theoretically overflow in the future, right now the values
fit.
Fixes: 18bb8bbf13 ("btrfs: zoned: automatically reclaim zones")

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.
