We have been embedding btrfs_delayed_ref_node in the btrfs_delayed_data_ref and btrfs_delayed_tree_ref, and then we have two sets of cachep's and a variety of handling that is awkward because of this separation. Instead union these two members inside of btrfs_delayed_ref_node and make that the first class object. This allows us to go down to one cachep for our delayed ref nodes instead of two.

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 reStructuredText 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.
