I was going to say, just pass the pgmap and lookup the altmap from pgmap, but Oscar added a use case for altmap independent of pgmap.

Other than that, looks good. _______________________________________________ Linux-nvdimm mailing list -- linux-nvdimm@lists.01.org To unsubscribe send an email to linux-nvdimm-le...@lists.01.org
