So that we can use it for multiple args, baby steps not to step into the verifier toes. In the process make sure we handle -EFAULT from bpf_prog_read_str(), as this really is needed now that we'll handle more than one augmented argument, i.e. if there is failure, then we have the argument that fails have: (size = 0, err = -EFAULT, value = [] ) followed by the next, lets say that worked for a second pathname: (size = 4, err = 0, value = "/tmp" ) So we can skip the first while telling the user about the problem and then process the second.
