I am pretty sure we can backport the changes. At least the NFS patch is
pretty straight forward (attached). The DHT fix needs a little more
attention while backporting (http://review.gluster.org/6219).

Do you have a bug for this against the 3.4 version? If not, please file
one and I'll post the NFS change for inclusion.

Note that 3.4.2 does not get any updates, you would need to use the 3.4
stable release series, currently at 3.4.6.
