From the fact that this is already in the RH bugzilla (private), I presume the issue is being worked on. CentOS will get the fix once it is in the RHEL kernel.
In the meantime, we can apply the patch to the centosplus kernel. |

kernel-plus-3.10.0-514.6.2.el7.centos.plus is out. It has the patch from this bug report. |

The patch is now in kernel-3.10.0-514.21.1.el7, so has been removed from the plus kernel. |
