The comment is wrong about the part where it says a prealloc extent does not contribute to an inode's nbytes - it does. Only holes don't contribute and that's what we are checking for, as prealloc extents always have a disk_bytenr different from 0. So fix the comment and re-organize the code to not set nbytes twice and set it to the extent item's number of bytes only if it doesn't represent a hole - in case it's a hole we have already initialized nbytes to 0 when we declared it.

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.
