Changes to the locking pattern protecting the event lists and handling of scsi command completion introduced a race where an ouststanding command that EH is waiting ifor to complete is no longer identifiable by being on the sent list, but instead as a command that is not on the free list. This is a result of moving commands to be completed off the sent list to a private list to be completed outside the list lock.
Second, during MQ enablement the ibmvfc_wait_for_ops helper used during EH to ensure commands were properely completed failed to be converted to check for commands on the sub-queues isntead of the primary CRQ.
