XFS inode chunks are already freed via deferred operations (which now also defer AGFL block frees), but inode btree blocks are freed directly in the associated context. This has been known to lead to log reservation overruns in particular workloads where an inobt block free may require several AGFL block frees (and thus several allocation btree modifications) before the inobt block itself is actually freed. To avoid this problem, defer the frees of any AGFL blocks before the inobt block free takes place. This requires passing the dfops from xfs_inactive_ifree() down through the inobt ->[alloc|free]_block() callouts, which essentially only requires to attach the dfops to the transaction since it is already carried all the way through to the inobt update and allocation.

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.
