user specific interruption parameter; will be presented back to cdev's interrupt handler. Allows a device driver to associate the
interrupt with a particular I/O request.

additional flags; defines the action to be performed for I/O processing.
timeout value in jiffies
Start a S/390 channel program. When the interrupt arrives, the IRQ handler is called, either immediately, delayed (dev-end missing, or
sense required) or never (no IRQ handler registered). This function notifies the device driver if the channel program has not completed
during the time specified by expires. If a timeout occurs, the channel program is terminated via xsch, hsch or csch, and the device's
interrupt handler will be called with an irb containing ERR_PTR(-ETIMEDOUT).
0, if the operation was successful; -EBUSY, if the device is busy, or status pending; -EACCES, if no path specified in lpm is operational;
-ENODEV, if the device is not operational.
Interrupts disabled, ccw device lock held
