I developed these changes some weeks ago but have since focused on
regression and performance testing on larger NUMA systems.
For regression testing I've been using mptest:

For performance testing I've been using a null_blk device (with
various configuration permutations, e.g. pinning memory to a
particular NUMA node, and varied number of submit_queues).
By eliminating multipath's heavy use of the m->lock spinlock in the
fast IO paths serious performance improvements are realized.
Hi Mike,
Are this the patches you pointed Hannes to?
If yes, please add my Tested-by: Johannes Thumshirn <jthumsh...@suse.de>
