    md/raid1: submit IO from originating thread instead of md thread. · f54a9d0e
    NeilBrown authored
    queuing writes to the md thread means that all requests go through the
    one processor which may not be able to keep up with very high request
    rates.
    
    So use the plugging infrastructure to submit all requests on unplug.
    If a 'schedule' is needed, we fall back on the old approach of handing
    the requests to the thread for it to handle.
