<div>Using ZFS as a backing filesystem may be a simpler way to go here if you want to stay with kernel.org. The lustre server + ZFS is patchless, and if you’re writing a new LND, you probably don’t care about the backing filesystem anyway.</div>

Why not work with the CentOS 7 kernel on the server anyway? Is something your LND needs not available? CentOS 7 is freely available and isn't far off in terms of kernel version from 3.12.<br>
<br>
You may be hard pressed to get useful advice on changing the ldiskfs patch series, that has the potential to be a pretty big job.<br>
