Subject: net/ipv6: Clean up rt expires helpers
X-Git-Tag: v4.19~872^2~416^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6a3e030f08e1b700aa6d1ebdc7ebe4c44a2ef67a;p=platform%2Fkernel%2Flinux-rpi.git

net/ipv6: Clean up rt expires helpers

rt6_clean_expires and rt6_set_expires are no longer used. Removed them.
rt6_update_expires has 1 caller in route.c, so move it from the header.
