Yonghong Song f6161a8f30 bpf: fix a compilation error when CONFIG_BPF_SYSCALL is not defined ... Kernel test robot (lkp@intel.com) reports a compilation error at https://www.spinics.net/lists/netdev/msg534913.html introduced by commit 838e96904f ("bpf: Introduce bpf_func_info"). If CONFIG_BPF is defined and CONFIG_BPF_SYSCALL is not defined, the following error will appear: kernel/bpf/core.c:414: undefined reference to `btf_type_by_id' kernel/bpf/core.c:415: undefined reference to `btf_name_by_offset' When CONFIG_BPF_SYSCALL is not defined, let us define stub inline functions for btf_type_by_id() and btf_name_by_offset() in include/linux/btf.h. This way, the compilation failure can be avoided.
