# CONFIG_ZRAM_BACKEND_ZSTD is not set

Comment 1 anotheruser 2024-12-22 03:44:03 UTC 
6.12.* kernels have CONFIG_ZRAM_BACKEND_FORCE_LZO  enabled.

this disables eny other comp algorithm for zram devices.

```
grep CONFIG_ZRAM_BACKEND_FORCE config-6.1*
config-6.12.5-200.fc41.x86_64:CONFIG_ZRAM_BACKEND_FORCE_LZO=y
config-6.12.6-200.fc41.x86_64:CONFIG_ZRAM_BACKEND_FORCE_LZO=y
```
