The ->write and ->wait fields of struct walk_control, used for log trees, are not used since 2008, more specifically since commitd0c803c404("Btrfs: Record dirty pages tree-log pages in an extent_io tree") and since commitd0c803c404("Btrfs: Record dirty pages tree-log pages in an extent_io tree"). So just remove them, along with the function btrfs_write_tree_block(), which is also not used anymore after removing the ->write member.

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.
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.
