Hello All,

Please find attached patch which adds new entry in existing zram device
sysfs interface, this interface shows compression ratio for asked zram
device.
Sysfs interface for 'orig_data_size' and 'mem_used_total' already present,
'compression_ratio' would be orig_data_size divided by mem_used_total.

Please check patch.
