2 bool "Dynamic compression of swap pages and clean pagecache pages"
3 depends on (CLEANCACHE || FRONTSWAP) && CRYPTO=y && ZSMALLOC=y
7 Zcache doubles RAM efficiency while providing a significant
8 performance boosts on many workloads. Zcache uses
9 compression and an in-kernel implementation of transcendent
10 memory to store clean page cache pages and swap in RAM,
11 providing a noticeable reduction in disk I/O.
