config ZRAM
tristate "Compressed RAM block device support"
depends on BLOCK
select LZO_COMPRESS
select LZO_DECOMPRESS
default n
help
Creates virtual block devices called /dev/zramX (X = 0, 1, ...).
Pages written to these disks are compressed and stored in memory
itself. These disks allow very fast I/O and compression provides
good amounts of memory savings.
It has several use cases, for example: /tmp storage, use as swap
disks and maybe many more.
See zram.txt for more information.

config ZRAM_STATS
bool "Enable statistics for compressed RAM disks"
depends on ZRAM
default y
help
Enable statistics collection for compressed RAM devices. Statistics
are exported through ioctl interface, so you have to use zramconfig
program to get them. This adds only a minimal overhead.
If unsure, say Y.
