Comment 5 for bug 1259570

The patch has been accepted upstream and is not in Linus's tree in 3.14-rc1 :

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7984754b99b6c89054edc405e9d9d35810a91d36

Kernel 3.13 is planned for Trusty but I will see if we can bring this patchset into Trusty
