From 3bf003335ba356aac5a43e28640159d4ae8a2a60 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Tue, 10 Jan 2017 15:02:16 +0100 Subject: [PATCH] bpf: Make unnecessarily global functions static MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Make the functions __local_list_pop_free(), __local_list_pop_pending(), bpf_common_lru_populate() and bpf_percpu_lru_populate() static as they are not used outide of bpf_lru_list.c This fixes the following GCC warnings when building with 'W=1': kernel/bpf/bpf_lru_list.c:363:22: warning: no previous prototype for ‘__local_list_pop_free’ [-Wmissing-prototypes] kernel/bpf/bpf_lru_list.c:376:22: warning: no previous prototype for ‘__local_list_pop_pending’ [-Wmissing-prototypes] kernel/bpf/bpf_lru_list.c:560:6: warning: no previous prototype for ‘bpf_common_lru_populate’ [-Wmissing-prototypes] kernel/bpf/bpf_lru_list.c:577:6: warning: no previous prototype for ‘bpf_percpu_lru_populate’ [-Wmissing-prototypes] Cc: Martin KaFai Lau Signed-off-by: Tobias Klauser Acked-by: Alexei Starovoitov Acked-by: Martin KaFai Lau Signed-off-by: David S.
