From 044bc355cdb57b05394902e60b75f9b39740a33a Mon Sep 17 00:00:00 2001 From: Joanne Koong Date: Thu, 16 Jun 2022 15:54:07 -0700 Subject: bpf: Fix non-static bpf_func_proto struct definitions [ Upstream commit dc368e1c658e4f478a45e8d1d5b0c8392ca87506 ] This patch does two things: 1) Marks the dynptr bpf_func_proto structs that were added in [1] as static, as pointed out by the kernel test robot in [2]. 2) There are some bpf_func_proto structs marked as extern which can instead be statically defined.
