2 tristate "Compressed RAM block device support"
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.
16 See zram.txt for more information.

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