Bug Description
I recently migrated to Mantic from Jammy and noticed that 6.5.0 has "DEAD" zswap. It also didn't work with HWE-6.5.0 (both -9 and -14) on Jammy.
Everything seems normal, all the parameters and no error msgs but frontswap stays 0k at all times and everything gets swapped directly to disk.
No usage is reported in /sys/module/
Jammy with HWE 6.2.0 and Mantic with https:/
I was able to reproduce the issue with https:/
(I would try the latest https:/
Seems like an upstream problem but not sure how to resolve it since Upstream 6.5 is abandoned and Jammy/Mantic 6.6 is months away...

Hi Eugene,
Can you try the latest 6.8-rc1 and let us know if it works there? Then we can see if we just need to backport a patch to 6.5, or talk to the upstream maintainers instead.
https:/ /kernel. ubuntu. com/mainline/ v6.8-rc1/
Thanks,
Matthew
