From: Dan Magenheimer <dan.magenheimer@xxxxxxxxxx> [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.
