Subject[PATCH 3.13.y-ckt 19/53] hpfs: kstrdup() out of memory handling
Date
3.13.11-ckt25 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sanidhya Kashyap <sanidhya.gatech@gmail.com>

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.
