The AGFL repair code uses a series of bitmaps to figure out where there are OWN_AG blocks that are not claimed by the free space and rmap btrees. These blocks become the new AGFL, and any overflow is reaped. The bitmaps current track xfs_fsblock_t even though we already know the AG number. In the last patch, we introduced a new bitmap "type" for tracking xfs_agblock_t extents. Port the reaping code and the AGFL repair to use this new type, which makes it very obvious what we're tracking. This also eliminates a bunch of unnecessary agblock <-> fsblock conversions.

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.
