To prepare for pending changes drop the optimization to only look up csums once per bio that is submitted from the iomap layer. In the short run this does cause additional lookups for fragmented direct reads, but later in the series, the bio based lookup will be used on the entire bio submitted from iomap, restoring the old behavior in common code.

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.
