8	  Creates virtual block devices called /dev/zramX (X = 0, 1, ...).
9	  Pages written to these disks are compressed and stored in memory
10	  itself. These disks allow very fast I/O and compression provides
11	  good amounts of memory savings.

13	  It has several use cases, for example: /tmp storage, use as swap
14	  disks and maybe many more.
