The xfs_btree_cur.bc_private.a.dfops field is only ever initialized by the refcountbt cursor init function. The only caller of that function with a non-NULL dfops is from deferred completion context, which already has attached to ->t_dfops. In addition to that, the only actual reference of a.dfops is the cursor duplication function, which means the field is effectively unused. Remove the dfops field from the bc_private.a union. Any future users can acquire the dfops from the transaction. This patch does not change behavior.

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.
