bpf: Make unnecessarily global functions static
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 <kafai@fb.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Acked-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: David S.
