Dysfunctional zcache in 3.0rc7 (Re: zcache: rename zcache.c to avoidbuild problem)

Hello,

in linux-3.0rc7 (and possibly others), zcache doesn't build correctly
-- zcache.o is omitted from linking. This results in kernel containing
tmem.o, but not zcache.o and no zcache functionality.

This issue (and also a patch) was previously mentioned at
https://patchwork.kernel.org/patch/903912/ , however no action was taken
up to now, and 3.0 release is really close. Patch mentioned above makes
zcache work properly.

Regards,
Milan Plzik
