From: Yasuyuki Kozakai Date: Tue, 12 Dec 2006 08:28:40 +0000 (-0800) Subject: [NETFILTER]: x_tables: error if ip_conntrack is asked to handle IPv6 packets X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fe0b9294c9f951a64c768f8a5879154235efe63f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git [NETFILTER]: x_tables: error if ip_conntrack is asked to handle IPv6 packets To do that, this makes nf_ct_l3proto_try_module_{get,put} compatible functions. As a result we can remove '#ifdef' surrounds and direct call of need_conntrack(). Signed-off-by: Yasuyuki Kozakai Signed-off-by: Patrick McHardy Signed-off-by: David S.
