Subject: [IPV6]: route6 remove ifdef for fib_rules
X-Git-Tag: v2.6.25-rc1~1162^2~1172
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7e5449c21562f1554d2c355db1ec9d3e4f434288;p=platform%2Fkernel%2Flinux-exynos.git

[IPV6]: route6 remove ifdef for fib_rules

The patch defines the usual static inline functions when the code is
disabled for fib6_rules. That's allow to remove some ifdef in route.c
file and make the code a little more clear.
