    blk-mq: allow resize of scheduler requests · 70f36b60
    Jens Axboe authored
    Add support for growing the tags associated with a hardware queue, for
    the scheduler tags. Currently we only support resizing within the
    limits of the original depth, change that so we can grow it as well by
    allocating and replacing the existing scheduler tag set.
    
    This is similar to how we could increase the software queue depth with
    the legacy IO stack and schedulers.
