Creates RAM based block devices (/dev/ramzswapX) which can be used (only) as swap disks. Pages swapped to these are compressed and stored in memory itself. The module is called ramzswap.ko. It depends on: - xvmalloc memory allocator (compiled with this driver) - lzo_compress.ko - lzo_decompress.ko See ramzswap.txt for usage details.
