Yeah, I think many error paths now might have memory leak, yet I'm not sure
if these does matter since the program would be exited soon... (since liberofs
doesn't export as a public library for now since I don't think these APIs are
finalized to public...)

Since there is the only one user of this label... So I think we might inline
such error path until more users exist?

Otherwise it looks good to me.

Thanks,
Gao Xiang
