Subject: staging: ramster: build ramster properly when CONFIG_OCFS2=m|y
X-Git-Tag: v3.4-rc1~186^2~130
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cb532e4b2bb2f156e9a6c2c4535334db764f603c;p=platform%2Fkernel%2Flinux-3.10.git

staging: ramster: build ramster properly when CONFIG_OCFS2=m|y

Due to some conflicting debug vars, kernel build will warn when
CONFIG_RAMSTER=y and CONFIG_OCFS2=m and will fail when
CONFIG_RAMSTER=y and CONFIG_OCFS2=y (rare).

Rename ramster mlog vars to avoid the name conflict.
