patch https://code.engineering.redhat.com/gerrit/#/c/59410/ and https://code.engineering.redhat.com/gerrit/#/c/59409/ available under coder review.
KP, could you have a look into these patches. I think these only 2 patches needed for 3.1.2
Verified with 3.1.2 build (glusterfs-3.7.5-0.3). seen there is only one epoll thread and ping timer set to zero. Moving this to verified state.
