Jens, ping?
Patch looks fine, and it looks completely bogus to set
null_mq_reg.nr_hw_queues
to 'nr_online_nodes', when we've potentially done "setup_queues()"
with just a single queue.
So I'm going to apply this as-is, I'm just wondering why I haven't
heard anything from you..

For NUMA systems, initializing the blk-mq layer and using per node hctx. We
initialize submit queues to 1, while blk-mq nr_hw_queues is initialized to the
number of NUMA nodes.
This makes the null_init_hctx function overwrite memory outside of what it
allocated. In my case it lead to writing
