6 tristate "Compressed RAM block device support"
7 depends on BLOCK && SYSFS
13 Creates virtual block devices called /dev/zramX (X = 0, 1, ...).
14 Pages written to these disks are compressed and stored in memory
15 itself. These disks allow very fast I/O and compression provides

18 It has several use cases, for example: /tmp storage, use as swap
19 disks and maybe many more.
21 See zram.txt for more information.
