can this work with HW accelerated compressors like the one in IBM Power
CPUs? See eg.
https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/W5...
Not sure, but it seems that zram currently supports only lzo and lz4
compression backends and boths are pure SW solutions. It does not use
IMB nx-compression (kernel ./drivers/crypto/nx/nx-842.c).
