Generally, the whole series looks great, but we must be missing one or
more patches here. I don't see the "nvme_map_data" part, which I suspect
is why this patch and others fail to apply using linux-block/for-next.
Once I clear up which patches to apply to which tree, I'd like to run
this through a few test systems to make sure there won't be any surprises.
