    libnvdimm: write blk label set · 0ba1c634
    Dan Williams authored
    After 'uuid', 'size', 'sector_size', and optionally 'alt_name' have been
    set to valid values the labels on the dimm can be updated.  The
    difference with the pmem case is that blk namespaces are limited to one
    dimm and can cover discontiguous ranges in dpa space.
    Also, after allocating label slots, it is useful for userspace to know
    how many slots are left.  Export this information in sysfs.
