Tyrel Datwyler 62fc266148 scsi: ibmvfc: Make ibmvfc_wait_for_ops() MQ aware ... During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was missed. This function is responsible for waiting on commands to complete that match a certain criteria such as LUN or cancel key. The implementation as is only scans the CRQ for events ignoring any sub-queues and as a result will exit successfully without doing anything when operating in MQ channelized mode. Check the MQ and channel use flags to determine which queues are applicable, and scan each queue accordingly. Note in MQ mode SCSI commands are only issued down sub-queues and the CRQ is only used for driver specific management commands. As such the CRQ events are ignored when operating in MQ mode with channels.
