Yu Zhao 14aa8b2d5c mm/mglru: don't sync disk for each aging cycle ... wakeup_flusher_threads() was added under the assumption that if a system runs out of clean cold pages, it might want to write back dirty pages more aggressively so that they can become clean and be dropped. However, doing so can breach the rate limit a system wants to impose on writeback, resulting in early SSD wearout.
