[PATCH V2 3/3] drivers/staging: zcache: misc build/config Makefiles and Kconfigs to build zcache in drivers/staging There is a dependency on xvmalloc.* which in 2.6.37 resides in drivers/staging/zram. Should this move or disappear, some Makefile/Kconfig changes will be required.

Zcache doubles RAM efficiency while providing a significant
|
|
performance boosts on many workloads. Zcache uses lzo1x
|
|
compression and an in-kernel implementation of transcendent
|
|
memory to store clean page cache pages and swap in RAM,
|
|
providing a noticeable reduction in disk I/O.
