Currently csum_tree_block() does two things, first it as it's name suggests it calculates the checksum for a tree-block. But it also writes this checksum to disk or reads an extent_buffer from disk and compares the checksum with the calculated checksum, depending on the verify argument. Furthermore one of the two callers passes in '1' for the verify argument, the other one passes in '0'. For clarity and less layering violations, factor out the second stage in csum_tree_block()'s callers.

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.
