As part of the memory management changes expected to be merged for the upcoming Linux 6.11 cycle is allowing more fine-tuned control over the swappiness setting used to determine how aggressively pages are swapped out of physical system memory and into the on-disk swap space.
This effectively allows more finer-grained control over the swapiness behavior without overriding the global swappiness setting.
Dan Schatzberg of Meta explains in the patch adding swappiness= support to memory.reclaim: Allow proactive reclaimers to submit an additional swappiness=[val] argument to memory.reclaim.
However, proactive reclaim runs continuously and so its impact on SSD write endurance is more significant.
Therefore, it’s desireable to have proactive reclaim reduce or stop swap-out before the threshold at which OOM killing occurs.
This has been in production for nearly two years and has addressed our needs to control proactive vs reactive reclaim behavior but is still not ideal for a number of reasons:

“However, plants such as mosses offer key benefits for terraforming, including stress tolerance, a high capacity for photoautotrophic growth, and the potential to produce substantial amounts of biomass under challenging conditions,” the new study’s team wrote in the paper.
The scientists subjected whole S. caninervis plants to conditions typically found on Mars: high doses of gamma radiation, low oxygen, extreme cold and drought.
“For example, S. caninervis plants maintain high levels of sucrose and maltose following stress; these sugars serve as osmotic agents and protectants that help preserve and stabilize cellular architecture,” wrote the scientists.
Stress also triggers genes that encode for photoprotective proteins and enzymes that help scavenge harmful reactive oxygen species generated under radiation.
Whether this statement is an exaggeration will depend on future experimentation — and may not even be achievable within our lifetime — but one important element missing from the discussion is not the feasibility of the science but the ethics behind it.
And, while the concept has been romanticized and thrown around in the media of late, there are serious concerns around social consequences on an extraterrestrial scale as a result of completely transforming an entire planet for human occupation.
