- Frontswap is so named because it can be thought of as the opposite
- of a "backing" store for a swap device. The data is stored into
- "transcendent memory", memory that is not directly accessible or
- addressable by the kernel and is of unknown and possibly
- time-varying size. When space in transcendent memory is available,
- a significant swap I/O reduction may be achieved. When none is
- available, all frontswap calls are reduced to a single pointer-
- compare-against-NULL resulting in a negligible performance hit
- and swap data is stored as normal on the matching swap device.
-
- If unsure, say Y to enable frontswap.
