10 in memory itself. These disks allow very fast I/O and compression provides
74 2) Set max number of compression streams
78 allocate multiple compression streams - one per online CPU - thus
79 allowing several concurrent compression operations. The number of
80 allocated compression streams goes down when some of the CPUs
81 become offline. There is no single-compression-stream mode anymore,
88 3) Select compression algorithm
92 currently selected (shown in square brackets) compression algorithms,
93 or change the selected compression algorithm (once the device is initialised
94 there is no way to change compression algorithm).

106 show every compression algorithm supported by the kernel. We keep this
108 a new device with a compression algorithm that is not listed in
113 custom crypto compression modules (implementing S/W or H/W compression).
