CONFIG_FRONTSWAP: Enable frontswap to cache swap pages if tmem is present

General informations

The Linux kernel configuration item CONFIG_FRONTSWAP:

Help text

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.
