1 # Compressed RAM block device support
3 Creates virtual block devices called /dev/zramX (X = 0, 1, ...). Pages written
4 to these disks are compressed and stored in memory itself. These disks allow
5 very fast I/O and compression provides good amounts of memory savings.
7 It has several use cases, for example: /tmp storage, use as swap disks and
8 maybe many more.
10 See Documentation/blockdev/zram.txt for more information.
