Now that the jobq holds a reference on the socket (in effect), I think that hold on the socket prevents release_offload_resources() from being called? If soref() alone doesn't prevent that, then I'm less certain this will actually be true.

On further thought, I think this is ok. If the jobq isn't empty, then at least one job exists, and that job would hold a reference on the struct file and thus keep the socket "open".
