Look at the new tools:

https://github.com/hakavlad/prelockd

https://github.com/hakavlad/memavaild

It can greatly improve responsiveness. Demo:

https://youtu.be/DsXEWvq60Rw - `tail /dev/zero`, swap on HDD, memavaild, no freezes

Very interesting: Should I still use nohang in addition to prelockd and memavaild? I mean prelockd could/should trigger the OOM earlier but nohang would still catch it earlier thanks to PSI?

What about zram and zswap advantages?

BTW you're helping making the world to be a better place but only nerds download those tools. It would help even more if you could lobby such tools as default in distros such as manjaro, arch, Ubuntu, fedora, etc
