Although it's not really my place to NAK, the maintainership was recently transitioned, so NAK. See this kernel thread http://www.gossamer-threads.com/lists/linux/kernel/1636154?do=post_view_threaded#1636154 for why.
See if this patch http://www.gossamer-threads.com/lists/linux/kernel/1660788 works for you instead.
