The following error was shown when a bpf program was compiled without vmlinux.h auto-generated from BTF: # clang -I./linux/tools/lib/ -I/lib/modules/$(uname -r)/build/include/ \ -O2 -Wall -target bpf -emit-llvm -c bpf_prog.c -o bpf_prog.bc ... In file included from linux/tools/lib/bpf/bpf_helpers.h:5: linux/tools/lib/bpf/bpf_helper_defs.h:56:82: error: unknown type name '__u64' ... It seems that bpf programs are intended for being built together with the vmlinux.h (which will have all the __u64 and other typedefs). But users may mistakenly think "include <linux/types.h>" is missing because the vmlinux.h is not common for non-bpf developers. IMO, an explicit comment therefore should be added to bpf_helpers.h as this patch shows.
