I finally enabled building this one (didn't realize it required ZCACHE
to be disabled, I can only build one or the other), and I noticed after
this patch the following warnings in my build:

drivers/staging/ramster/zcache-main.c:950:13: warning: ‘zcache_do_remotify_ops’ defined but not used [-Wunused-function]
drivers/staging/ramster/zcache-main.c:1039:13: warning: ‘ramster_remotify_init’ defined but not used [-Wunused-function]
drivers/staging/ramster/zcache-main.c: In function ‘zcache_put’:
drivers/staging/ramster/zcache-main.c:1594:4: warning: ‘page’ may be used uninitialized in this function [-Wuninitialized]
drivers/staging/ramster/zcache-main.c:1536:8: note: ‘page’ was declared here

Care to please fix them up?

thanks,
