The comment at the top of btrfs_truncate() mentions that csum items are dropped or truncated to the new i_size, but this is wrong and non sense, as they are unrelated to the i_size and are located in the csums tree and not on a tree with inode items (fs/subvolume tree or a log tree). Instead that claim applies to file extent items, so fix the comment to refer to them instead. While at it make the whole comment for the function more descriptive and follow the kernel doc style.

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.
