Subject: [PATCH 1/1] 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.
