From 4cbd23cc92c49173e402753cab62b8a7754ed18f Mon Sep 17 00:00:00 2001 From: Martin KaFai Lau Date: Tue, 7 Mar 2023 22:59:20 -0800 Subject: [PATCH] bpf: Move a few bpf_local_storage functions to static scope This patch moves the bpf_local_storage_free_rcu() and bpf_selem_unlink_map() to static because they are not used outside of bpf_local_storage.c.
