From: Florian Westphal Date: Tue, 7 Nov 2017 06:20:09 +0000 (+0100) Subject: netfilter: conntrack: l4 protocol trackers can be const X-Git-Tag: v5.15~9522^2~216^2~49 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9dae47aba0a055f761176d9297371d5bb24289ec;p=platform%2Fkernel%2Flinux-starfive.git netfilter: conntrack: l4 protocol trackers can be const previous patches removed all writes to these structs so we can now mark them as const.
