generic: 5.15: move MGLRU patches from pending to backport

Move MGLRU patches from pending to backport as they got merged upstream.
These are direct porting from one of the dev so it's better to just move
than trying to backport them again from upstream.

+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.
