The kernel patches for a specific Lustre release are only sure to work for the kernel version described in lustre/ChangeLog. They may work on earlier or later kernels (chance is proportional to the difference of the kernel version :-). In general, we discourage people building server kernels for different kernels, because the servers should only be running Lustre, and can run the specific kernel version that is known to work with that version of Lustre. You can download the exact matching kernel sources at http://downloads.lustre.org/ so that you are sure to get a matching kernel.
