4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sanidhya Kashyap <[email protected]> commit ce657611baf902f14ae559ce4e0787ead6712067 upstream. There is a possibility of nothing being allocated to the new_opts in case of memory pressure, therefore return ENOMEM for such case.
