Factor out the inner loop of raid5_make_request() into it's own helper called make_stripe_request(). The helper returns a number of statuses: SUCCESS, RETRY, SCHEDULE_AND_RETRY and FAIL. This makes the code a bit easier to understand and allows the SCHEDULE_AND_RETRY path to be made common. A context structure is added to contain do_flush. It will be used more in subsequent patches for state that needs to be kept outside the loop. No functional changes intended. This will be cleaned up further in subsequent patches to untangle the gen_lock and do_prepare logic further.

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.
