From cc2e0b3fbcdd9667d7b7ecdf36d7b4d3647681d6 Mon Sep 17 00:00:00 2001 From: Brenden Blanco Date: Wed, 20 Jul 2016 07:55:52 -0700 Subject: bpf: fix implicit declaration of bpf_prog_add For the ifndef case of CONFIG_BPF_SYSCALL, an inline version of bpf_prog_add needs to exist otherwise the build breaks on some configs. drivers/net/ethernet/mellanox/mlx4/en_netdev.c:2544:10: error: implicit declaration of function 'bpf_prog_add' prog = bpf_prog_add(prog, priv->rx_ring_num - 1); The function is introduced in 59d3656d5bf50 ("bpf: add bpf_prog_add api for bulk prog refcnt") and first used in 47f1afdba2b87 ("net/mlx4_en: add support for fast rx drop bpf program"). Fixes: 47f1afdba2b87 ("net/mlx4_en: add support for fast rx drop bpf program") Reported-by: kbuild test robot Reported-by: Tariq Toukan Signed-off-by: Brenden Blanco Acked-by: Alexei Starovoitov Signed-off-by: David S.
