The 'start' variable indicates the start of a filemap and is set to the iocb's position, which we have already cached as 'pos', upon function entry. 'pos' is used as a cursor indicating the current position and updated later in iomap_dio_rw(), but not before the last use of 'start'. Remove 'start' as it's synonym for 'pos' before we're entering the loop calling iomapp_apply().

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.
