The lookup currently either returns the cached filestream AG or it calls xfs_filestreams_select_lengths() to looks up a new AG. This has verify the AG that is selected, so we end up doing "select a new AG loop in a couple of places when only one really is needed. Merge the initial lookup functionality with the length selection so that we only need to do a single pick loop on lookup or verification failure. This undoes a lot of the factoring that enabled the selection to be moved over to the filestreams code. It makes xfs_filestream_select_ag() an awful messier, but it has to be made worse before it can get better in future patches...

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.
