Now that AGFL block frees are deferred when dfops is set in the transaction, start deferring AGFL block frees from contexts that are known to push the limits of existing log reservations. The first such context is deferred operation processing itself. This primarily targets deferred extent frees (such as file extents and inode chunks), but in doing so covers all allocation operations that occur in deferred operation processing context. Update xfs_defer_finish() to set and reset ->t_agfl_dfops across the processing sequence. This means that any AGFL block frees due to allocation events result in the addition of new EFIs to the dfops rather than being processed immediately. xfs_defer_finish() rolls the transaction at least once more to process the frees of the AGFL blocks back to the allocation btrees and returns once the AGFL is rectified.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
