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

19 bool "Enable statistics for compressed RAM disks"
23 Enable statistics collection for compressed RAM devices. Statistics
24 are exported through ioctl interface, so you have to use zramconfig
25 program to get them. This adds only a minimal overhead.
