Take it as one, I think it's what should have been in the cset it isfixing, that way no breakage would have happened. Ok. I trimmed commit log and applied here: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git/commit/?id=1fd450f99272791df8ea8e1b0f5657678e118e90 What about your other fix and my suggestion there? (__u64) cast instead of PRI ? We do this already in two places: libbpf.c: shdr_idx, (__u64)sym->st_value); libbpf.c: (__u64)sym.st_value, GELF_ST_TYPE(sym.st_info),
I'm using the smartphone now, but I thought you first suggested using a cast to long, if you mean using %llu + cast to __u64, then should be was ugly as using PRI, IOW, should work on both 64 bit and 32 bit. :-) - Arnaldo
