5 Device-Mapper's "zero" target provides a block-device that always returns
6 zero'd data on reads and silently drops writes. This is similar behavior to
7 /dev/zero, but as a block-device instead of a character-device.
9 Dm-zero has no target-specific parameters.
11 One very interesting use of dm-zero is for creating "sparse" devices in
15 device. Reads to previously unwritten areas will return a zero'd buffer. When
20 To create a sparse device, start by creating a dm-zero device that's the
