From: Alexei Starovoitov Date: Tue, 7 Dec 2021 01:48:39 +0000 (-0800) Subject: bpf: Silence purge_cand_cache build warning. X-Git-Tag: v6.1-rc5~2306^2~228^2~8 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=29f2e5bd9439445fe14ba8570b1c9a7ad682df84;p=platform%2Fkernel%2Flinux-starfive.git bpf: Silence purge_cand_cache build warning. When CONFIG_DEBUG_INFO_BTF_MODULES is not set the following warning can be seen: kernel/bpf/btf.c:6588:13: warning: 'purge_cand_cache' defined but not used [-Wunused-function] Fix it. Fixes: 1e89106da253 ("bpf: Add bpf_core_add_cands() and wire it into bpf_core_apply_relo_insn().")
