So the kernel supports zswap but it is currently NOT enabled.

When system is booted the following journal message appears

kernel: zswap: loaded using pool lzo/zbud

ps aux | grep -i zswap

returns

root 135 0.0 0.0 0 0 ? I< Feb09 0:00 [zswap-shrink]

If zswap is NOT enabled, why is zswap loaded with a pool at boot time and why is the zswap-shrink process running?

I find that the same situation on a TW test machine I have that is running the 5.16.5.2 kernel so it is not an isolated case.

Is this a bug? Maybe kernel@lists.opensuse.org is more appropriate (cc'ing).
