When an I/O request is made, the fsm_io_request() routine moves the FSM state from IDLE to CP_PROCESSING, and then fsm_io_helper() moves it to CP_PENDING if the START SUBCHANNEL received a cc0. Yet, the error case to go from CP_PROCESSING back to IDLE is done after the FSM call returns. Let's move this up into the FSM proper, to provide some better symmetry when unwinding in this case.

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.
