6.12 kernel reworked how ZRAM backends were configured. Let's enable the ones we've lost. I've chosen zstd as the default. 6.6 kernel supported: $ cat /sys/block/zram0/comp_algorithm [lzo-rle] lzo lz4 zstd 6.12 currently supports: $ cat /sys/block/zram0/comp_algorithm [lzo-rle] lzo With this PR 6.12 supports: $ cat /sys/block/zram0/comp_algorithm lzo-rle lzo lz4 [zstd] See: https://forums.raspberrypi.com/viewtopic.php?p=2296678#p2296678 Signed-off-by: Dom Cobley <popcornmix@gmail.com>

I'm happy to change the default and/or what's enabled if anyone feels strongly. |

6.12 kernel reworked how ZRAM backends were configured. Let's enable the ones we've lost.
I've chosen zstd as the default.
6.6 kernel supported:
$ cat /sys/block/zram0/comp_algorithm
[lzo-rle] lzo lz4 zstd
6.12 currently supports:
$ cat /sys/block/zram0/comp_algorithm
[lzo-rle] lzo
With this PR 6.12 supports:
$ cat /sys/block/zram0/comp_algorithm
lzo-rle lzo lz4 [zstd]
