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. | |
