From e794bfddb8b8521bd016e73b411d6b03149e9e66 Mon Sep 17 00:00:00 2001 From: Martin KaFai Lau Date: Thu, 12 Nov 2020 13:13:07 -0800 Subject: bpf: Rename some functions in bpf_sk_storage Rename some of the functions currently prefixed with sk_storage to bpf_sk_storage. That will make the next patch have fewer prefix check and also bring the bpf_sk_storage.c to a more consistent function naming.
