In several places we iterate every AG from a specific start agno and wrap back to the first AG when we reach the end of the filesystem to continue searching. We don't have a primitive for this iteration yet, so add one for conversion of these algorithms to per-ag based iteration. The filestream AG select code is a mess, and this initially makes it worse. The per-ag selection needs to be driven completely into the filestream code to clean this up and it will be done in a future patch that makes the filestream allocator use active per-ag references correctly.

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.
