This patch introduces a new parser helper, parse_u64_with_suffix(), which has a better error handling, following all the parse_*() helpers to return non-zero value for errors. This new helper is going to replace parse_size_from_string(), which would directly call exit(1) to stop the whole program. Furthermore most callers of parse_size_from_string() are expecting exit(1) for error, so that they can skip the error handling. For those call sites, introduce a wrapper, arg_strtou64_with_suffix(), to do that. The only disadvantage is a little less detailed error report for why the parse failed, but for most cases the generic error string should be enough.
