1. Please describe the problem: egrep ZSTD config-6.12.4-200.fc41.x86_64 # CONFIG_ZRAM_BACKEND_ZSTD is not set 2. What is the Version-Release number of the kernel: 6.12.4-200.fc41.x86_64 Reproducible: Always
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 ```
