I guess you are trying to use the mainline version of zram -- zramconfig is
now gone as we want to switch to /sys interface instead. Currently, mainline
version is in a bit inconsistent state and some important fixes have not yet
reached mainline due to time constraints. I hope to fix that in near future.
 In the mean time, please use zram code from project hg repository.

Thanks,
Nitin
