Log recovery passes down a central dfops structure to recovery handlers for bui and cui log items. Each of these handlers allocates and commits a transaction and defers any remaining operations to be completed by the main recovery sequence. Since dfops outlives the transaction in this context, set and clear ->t_dfops appropriately such that the *_finish_item() paths and below (i.e., xfs_bmapi*()) can expect to find the dfops in the transaction without it being committed with the dfops attached. This is required because transaction commit expects that an associated dfops is finished and in this context the dfops may be populated at commit time.

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.
