Is that your nvme preference - if less than 4 streams, just ignore it? Would seem a shame to lose out with 2 streams, I can think of several hot/cold scenarios that would probably work fine with that. But at the same time, not a big deal to me, if you prefer just turning it off for < 4 streams, that's fine with me. -- Jens Axboe
