Hence a checkpoint\ncreated on such a path would prune against arbitrary scalar value.\n\ncheck_helper_call() enforces second parameter of the\nbpf_get_local_storage() to be zero, w/o marking the underlying scalar\nregister precise. Hence a checkpoint created on such a path would\nprune against arbitrary scalar value.\n\nGrouping these two into one patch, as they share the same fixes tag.",
