We currently don't have any flags or operational state in the xfs_perag except for the pagf_init and pagi_init flags. And the agflreset flag. Oh, there's also the pagf_metadata and pagi_inodeok flags, too. For controlling per-ag operations, we are going to need some atomic state flags. Hence add an opstate field similar to what we already have in the mount and log, and convert all these state flags across to atomic bit operations.

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.
