+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.

+Fixes: bd74fdaea146 ("mm: multi-gen LRU: support page table walks")
