Subject: [PATCH V2 3/3] drivers/staging: zcache: misc build/config
Date: Sun, 6 Feb 2011 19:27:09 -0800 [thread overview]
Message-ID: <20110207032709.GA27475@ca-server1.us.oracle.com> (raw)
[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.
