Christof Schmitt 143bb6bfe3 [SCSI] zfcp: Defer resource allocation to first ccw_set_online call ... So far, zfcp allocated all resources required for FCP adapters/subchannels when the device was discovered in the ccw_probe callback. If there are lots of unused FCP subchannels attached to a system, this is a waste of resources. To alleviate this, defer the resource allocation to the first call to ccw_set_online. To avoid disruptions during possible following calls to ccw_set_offline and then ccw_set_online, keep the adapter resources until the device is finally being removed via ccw_remove. While doing this, also manage the zfcp erp thread together with all other adapter resources in zfcp_adapter_enqueue/dequeue.
