    [PATCH] Add blk_start_queueing() helper · dc72ef4a
    Jens Axboe 提交于
    CFQ implements this on its own now, but it's really block layer
    knowledge. Tells a device queue to start dispatching requests to
    the driver, taking care to unplug if needed. Also fixes the issue
    where as/cfq will invoke a stopped queue, which we really don't
    want.
