Alexander Motin dcf7044522 Fix for "Reduce latency effects of non-interactive I/O" ... It was found that setting min_active tunables for non-interactive I/Os makes them stuck. It is caused by zfs_vdev_nia_delay, that can never be reached if we never issue any I/Os due to min_active set to zero. Fix this by issuing at least one non-interactive I/O at a time when there are no interactive I/Os. When there are interactive I/Os, zero min_active allows to completely block any non-interactive I/O. It may min_active starvation in some scenarios, but who we are to deny foot shooting?
