Previously, the code which printed io.stat only needed access to the generic rstat flushing code, but since we plan to write some more specific code for preparing root cgroup stats, we need to manipulate iostat structs directly. Since declaring static functions ahead does not seem like common practice in this file, simply move the iostat functions up. We only plan to use blkg_iostat_set, but it seems better to keep them all together.

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.
