Subject: [PATCH 0/2] zram: introduce compressed data writeback

As writeback becomes more common there is another shortcoming
that needs to be addressed - compressed data writeback.  Currently
zram does uncompressed data writeback which is not optimal due to
potential CPU and battery wastage.  This series changes suboptimal
uncompressed writeback to a more optimal compressed data writeback.
