From: Andrii Nakryiko <[email protected]> Using %ld for printing out value of ptrdiff_t type is not portable between 32-bit and 64-bit archs. This is causing compilation errors for libbpf on 32-bit platform (discovered as part of an effort to integrate libbpf into systemd ([0])). Proper formatter is %td, which is used in this patch.
