    UBI: add ubi_leb_map interface · 393852ec
    Artem Bityutskiy 提交于
    The idea of this interface belongs to Adrian Hunter. The
    interface is extremely useful when one has to have a guarantee
    that an LEB will contain all 0xFFs even in case of an unclean
    reboot. UBI does have an 'ubi_leb_erase()' call which may do
    this, but it is stupid and ineffecient, because it flushes whole
    queue. I should be re-worked to just be a pair of unmap,
    map calls.
    
    The user of the interfaci is UBIFS at the moment.
