    block: reorganize QUEUE_ORDERED_* constants · 313e4299
    Tejun Heo authored
    Separate out ordering type (drain,) and action masks (preflush,
    postflush, fua) from visible ordering mode selectors
    (QUEUE_ORDERED_*).  Ordering types are now named QUEUE_ORDERED_BY_*
    while action masks are named QUEUE_ORDERED_DO_*.
    
    This change is necessary to add QUEUE_ORDERED_DO_BAR and make it
    optional to improve empty barrier implementation.
