When removing chunk from a tree, we do shrink the chunk. This can fail for various reasons (due to races, ENOMEM, etc.) and in some cases we just bail from untag_chunk() relying on someone else to cleanup. Although this currently works, later we will need to add new failure situation which would break. Also this simplifies the code and will allow us to make locking around untag_chunk() less awkward.

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.
