Add the internal logic to check for autoquiesce triggers and handle them. Quiesce and resume are functions that tell Linux to stop/resume issuing I/Os to a specific DASD. The DASD driver allows a manual quiesce/resume via ioctl. Autoquiesce will define an amount of triggers that will lead to an automatic quiesce if a certain event occurs. There is no automatic resume. All events will be reported via DASD Extended Error Reporting (EER) if configured.
