Had you use Ubuntu you could probably say something like "kernel 4.2
should be released as linux-generic-lts-wily for ubuntu 14.04 in about
two months, and we can switch to distro-supported package then"

Had you use Oracle Linux with support subscription, you could probably
nag them about when they would relase unbreakable enterprise kernel
release 4, which should be newer kernel, with some features added by
oracle, tested and supported to run on oracle linux (which is mostly a
clone of RHEL, with some additions)

Had you use RHEL with support subscription, you could probably ask
Redhat to backport kernel fix for this particular issue to RHEL 7's
kernel.

Since you use Centos, your best bet would probably:
- Hope someone else nags Redhat, so the fix would eventually trickle
down to centos. OR
- Use 4.2 kernel, with its consequences (e.g. not tested and supported
by redhat). OR
- Try kernel 4.1. That version should be an LTS kernel, and elrepo
would probably release kernel-lt 4.1 for rhel/centos7 (like they did
with rhel/centos 5 and 6) sometime in the future. Being longterm
kernel, you should be able to stick with kernel 4.1.x for a few years,
without having to upgrade to mainline/stable kernel.
