James Smart a7d139145a nvme-fc: clear q_live at beginning of association teardown ... The __nvmf_check_ready() routine used to bounce all filesystem io if the controller state isn't LIVE. However, a later patch changed the logic so that it rejection ends up being based on the Q live check. The FC transport has a slightly different sequence from rdma and tcp for shutting down queues/marking them non-live. FC marks its queue non-live after aborting all ios and waiting for their termination, leaving a rather large window for filesystem io to continue to hit the transport. Unfortunately this resulted in filesystem I/O or applications seeing I/O errors. Change the FC transport to mark the queues non-live at the first sign of teardown for the association (when I/O is initially terminated).
