3 # X86 dependency is because zsmalloc uses non-portable pte/tlb
5 depends on BLOCK && SYSFS && X86
11 Creates virtual block devices called /dev/zramX (X = 0, 1, ...).
12 Pages written to these disks are compressed and stored in memory
13 itself. These disks allow very fast I/O and compression provides
14 good amounts of memory savings.
16 It has several use cases, for example: /tmp storage, use as swap
17 disks and maybe many more.
19 See zram.txt for more information.
