[CentOS] Fix for RHEL BZ#771868 in CentOS?

Hey,

We are blocked on a bug fixed by RHEL in
https://rhn.redhat.com/errata/RHBA-2012-0362.html. Specifically, the splice
code in sendfile() incorrectly updating the offset position on the write
side, Red Hat BZ#771868.

I have not been able to figure out if this bugfix is included in any CentOS
releases. If you are better at reading release notes than me, could you
please help me out and let me know if there's a CentOS release that
includes this bugfix?

Thanks,
Jeff
