The ramzswap module creates RAM based block devices which can (only) be used as

swap disks. Pages swapped to these devices are compressed and stored in memory

itself. See project home for use cases, performance numbers and a lot more.



Individual ramzswap devices are configured and initialized using rzscontrol

userspace utility as shown in examples below. See rzscontrol man page for more
