On the other end lustre also has been ported to platforms like ARM and KNL which have uniquie NUMA and core setup. For example some devices exist that have NUMA nodes with no cores. With these new platforms the limitations of the Lustre's SMP code came to light so a lot of work was needed. This resulted in this patch set which has been tested on these platforms.
