per Ubuntu:
https://askubuntu.com/questions/471912/zram-vs-zswap-vs-zcache-ultimate-guide-when-to-use-which-one

my solution was to turn off non-zram swap devices after initialization:

...
swapon -p 5 /dev/zram3

swapon -s
for i in $( swapon -s | awk 'NR>1 { print $1 }' | egrep -v zram ) ; do swapoff ${i} ; done
swapon -s

Existing swap is disabled before creating the ZRAM swap in PR #3 - I tested your code first but it didn't work. I just took a different approach and instead turned off existing swap before enabling ZRAM.
