[PATCH] s390: dasd ioctl never returns
The dasd state machine is not designed to enable an unformatted device, since
'unformatted' is a final state. The BIODASDENABLE ioctl calls
dasd_enable_device() which never returns if the device is in this special
state. Return -EPERM in dasd_increase_state for unformatted devices to make
dasd_enable_device terminate. Note: To get such an unformatted device online
it has to be re-analyzed. This means that the device needs to be disabled
prior to re-enablement.
