obj_req->xferred and img_req->xferred don't bring any value. The former is used for short reads and has to be set to obj_req->ex.oe_len after that and elsewhere. The latter is just an aggregate. Use result for short reads (>=0 - number of bytes read, <0 - error) and pass it around explicitly. No need to store it in obj_req.

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.
