The ->lazy_len is only checked locklessly. Recheck again under the ->nocb_lock to avoid spending more time on flushing/waking if not necessary. The ->lazy_len can still increment concurrently (from 1 to infinity) but under the ->nocb_lock we at least know for sure if there are lazy callbacks at all (->lazy_len > 0).
