netfilter: bpf: Only define get_proto_defrag_hook() if necessary
Before, we were getting this warning: net/netfilter/nf_bpf_link.c:32:1: warning: 'get_proto_defrag_hook' defined but not used [-Wunused-function] Guard the definition with CONFIG_NF_DEFRAG_IPV[4|6]. Fixes: 91721c2d02d3 ("netfilter: bpf: Support BPF_F_NETFILTER_IP_DEFRAG in netfilter link") Reported-by: kernel test robot <[email protected]> Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/ Signed-off-by: Daniel Xu <[email protected]> Link: https://lore.kernel.org/r/b128b6489f0066db32c4772ae4aaee1480495929.1690840454.git.dxu@dxuuu.xyz Signed-off-by: Alexei Starovoitov <[email protected]>
