    libnvdimm: pmem label sets and namespace instantiation. · bf9bccc1
    Dan Williams authored
    A complete label set is a PMEM-label per-dimm per-interleave-set where
    all the UUIDs match and the interleave set cookie matches the hosting
    interleave set.
    Present sysfs attributes for manipulation of a PMEM-namespace's
    'alt_name', 'uuid', and 'size' attributes.  A later patch will make
    these settings persistent by writing back the label.
    Note that PMEM allocations grow forwards from the start of an interleave
    set (lowest dimm-physical-address (DPA)).  BLK-namespaces that alias
    with a PMEM interleave set will grow allocations backward from the
    highest DPA.
