We have the inode locked so no one can concurrently change its i_size and neither do we change it ourselves, so there's no point in keep rounding it in the while loop and setting it up in the control structure. That only causes confusion when reading the code. So move all the i_size setup and rounding out of the loop and assert the inode is locked.

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.
