xfs_itruncate_extents[_flags]() uses a local dfops with a transaction provided by the caller. It uses hacky ->t_dfops replacement logic to avoid stomping over an already populated ->t_dfops. The latter never occurs for current callers and the logic itself is not really appropriate. Clean this up by updating all callers to initialize a dfops and to use that down in xfs_itruncate_extents(). This more closely resembles the upcoming logic where dfops will be embedded within the transaction. We can also replace the xfs_defer_init() in the xfs_itruncate_extents_flags() loop with an assert. Both dfops and firstblock should be in a valid state after xfs_defer_finish() and the inode joined to the dfops is fixed throughout the loop.

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.
