For lustre client, we did not need to alter our kernel at all. We just made and installed lustre-1.8.5 and lustre-modules-1.8.5 rpms. /etc/ modprobe.conf needs a tweak.
For lustre server, I believe you will need to deal with a patched kernel. We have not been down this road yet since our vendor includes lustre server software with their hardware.
