    md/raid5: add simple plugging infrastructure. · 2ac87401
    NeilBrown authored
    md/raid5 uses the plugging infrastructure provided by the block layer
    and 'struct request_queue'.  However when we plug raid5 under dm there
    is no request queue so we cannot use that.
    
    So create a similar infrastructure that is much lighter weight and use
    it for raid5.
