Some archs, like arm64, use userspace pt_regs in bpf_tracing.h. When cross compiling arm64 bpf examples in x86_64 host, clang cannot find the arch specific uapi ptrace.h, which causing below compiling errror, " uprobe.bpf.c:11:5: error: incomplete definition of type 'struct user_pt_regs' 11 | int BPF_KPROBE(uprobe_add, int a, int b) " Using arch specific vmlinux.h fix this issue.
