How to enable zramfs in android...

[sandeep kumar]

>>In my system /dev/zram0 is not present but sys/block/zram0 is present.
thats why i m having this doubt
just now i found that we have zram0 in /dev/block/zram0
i tried the command you told,

*root at kleoslte:/ # swapon -p 100 /dev/block/zram0*
*swapon -p 100 /dev/block/zram0*
*swapon failed for /dev/block/zram0*

is there anything else that i can try?
