One of the final things that must be done to add a new chunk is inserting its device extent items in the device tree. They describe the portion of allocated device physical space during phase 1 of chunk allocation. This is currently done in btrfs_finish_chunk_alloc whose name isn't very informative. What's more, this function is only used in block-group.c but is defined as public. There isn't anything special about it that would warrant it being defined in volumes.c. Just move btrfs_finish_chunk_alloc and alloc_chunk_dev_extent to block-group.c, make the former static and rename both functions to insert_dev_extents and insert_dev_extent respectively.

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.
