Using that v5 for some time and confirm that difference under heavy load and memory pressure is significant.

Appreciate the heads up, Michael. Looking forward to the benchmarks on these. I was using the MGLRU patches on 5.15 but they weren't patching cleanly on 5.16.
Can confirm the new v6 patchset patches cleanly on 5.16-rc8. Good stuff.
I have it disabled by default in the kernel config, but it can be manually enabled via the following:
Code:$ uname -a Linux ryzen 5.16-rc8-051600rc8+customidle-generic #051600rc8+202107311230 SMP PREEMPT Sun Jan 9 02:54:46 PST 2022 x86_64 x86_64 x86_64 GNU/Linux $ cat /sys/kernel/mm/lru_gen/enabled 0 $ echo 1 | sudo tee /sys/kernel/mm/lru_gen/enabled 1 $ cat /sys/kernel/mm/lru_gen/enabled 1

But, no, seriously, I switched zram off, made a 1GB swap file on the flash storage (microSD is just way too slow, tried it) and raised swappiness from 25 to 50 and haven't had OOM kills since...

Going back a number of months Google engineers have been working to address the issue of the Linux kernel's page reclaim code being too expensive for which they devised the multi-generational LRU framework "MGLRU" and it continues being worked on with mainline ambitions...
