I'm trying to enable zswap on my digitalocean Ubuntu 16.04 droplet without any luck.
I tried to apend
zswap.enabled=1 to grub's
GRUB_CMD_LINUX_DEFAULT and to
GRUB_CMD_LINUX and after that run
I also trie to enable it in runtime by executing
echo 1 > /sys/module/zswap/parameters/enabled as suggested by ArchWiki but it tells me that
/sys/module/zswap/parameters/enabled: No such file or directory, folder parameters contains only max_pool_percent.
As I've read zswap was merged into 3.11 kernel and I have
dmesg | grep zswap shows nothing. Is there any way I can enable it in such configuration?
