This function currently takes 7 parameters, most of which are proxies for values from btrfs_delayed_ref_node struct which is not passed. This patch simplifies the interface of the function by simply passing said delayed ref node struct to the function. This enables us to: 1. Move locals variables and init code related to them from run_delayed_tree_ref which should only be used inside alloc_reserved_tree_block, such as skinny_metadata and the btrfs_key, representing the extent being inserted. This removes the need for the "ins" argument. Instead, it's replaced by a local var with a more verbose name - extent_key. 2. Now that we have a reference to the node in alloc_reserved_tree_block the delayed_tree_ref struct can be referenced inside the function and this enable removing the "ref->level", "parent" and "ref_root" arguments.

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.
