Julian Wiedmann b39544c6e0 s390/qdio: pass up count of ready-to-process SBALs
When qdio_{in,out}bound_q_moved() scans a queue for pending work, it
currently only returns a boolean to its caller. The interface to the
upper-layer-drivers (qdio_kick_handler() and qdio_get_next_buffers())
then re-calculates the number of pending SBALs from the
q->first_to_check and q->first_to_kick cursors.

Refactor this so that whenever get_{in,out}bound_buffer_frontier()
adjusted the queue's first_to_check cursor, it also returns the
corresponding count of ready-to-process SBALs (and 0 else).
A subsequent patch will then make use of this additional information.

README

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.
