In an all paths down scenario I/O will be requeued or aborted, and no further I/O will be ongoing on this namespace. This leaves the upper layers unable to determine if the namespace becomes operational again eg. after a successful controller reset. With this patch a 'change' uevent will be sent per multipathed namespace once the underlying controller moved to LIVE and started I/O processing by calling nvme_kick_requeue_lists().
